Book excerpt: Virtual test methods can contribute to reducing the great effort for physical tests in the development of lightweight products. The present work describes an approach for virtual testing of sandwich panel joints based on the Building Block Approach and the Finite Elements Method. Building on a multitude of physical tests on sandwich materials and joints, adequate sub-models are developed, validated and synthesized to top-level models. The developed approach is eventually applied for the development of a novel sandwich panel joint.

This book was released on 1996 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: The indentation behavior of aircraft floor panels (honeycomb sandwich structures) was investigated from the viewpoints of test methodology, effects of panel construction, and failure mechanisms. An indentation test method using a simply-supported plate was developed to replicate observed in-use failure modes. The localization and type of damage induced with this test method correlated extremely well with damage present in panels returned from airlines suggesting that highly-concentrated loads, such as from high heels, cause most panel damage. Furthermore, damage appeared to spread due to an accumulation of multiple damage events more so than propagating from only a few. Both aramid- and aluminum-cored panels showed failures that occurred just below the resin fillet on the top skin. Aramid failed in brittle compression and post-buckling whereas aluminum failed due to ductile buckling. These results strongly indicate that near-surface properties dominate indentation behavior in contrast to the core-dominated stabilized core compression test as well as the skin-dominated failure criteria used in ASTM-type impact tests. Indentation tests using various skin and core constructions demonstrated the influence of changing core density, core material, and skin construction as well as the synergistic effect of skin and core on indentation damage resistance. Several analytical models were examined to aid in understanding the failure mechanisms due to indentation. These suggest that large local skin deflections are important in local load redistribution leading to core failure.

Book excerpt: Bachelor Thesis from the year 2014 in the subject Engineering - Aerospace Technology, grade: 1,3, Hamburg University of Applied Sciences, course: Sandwichstrukturen, language: English, abstract: With the proceeding technologies in full automatic CNC machines, this valuable resource raises the question whether panel pins are still the most effective way to build cabinets. Different ways for panel joints are discussed and a concept for a potentially more effective way will be elaborated and tested. In preparation for the engineering of a new panel joint, which would change the industry standard, design standards and guidelines for developing test coupons are analyzed and provided. Following the first designs of test coupons in the CAD system Solidworks is a company test to prove the strength for tension and shear loads. Furthermore, a value analysis will be created to prove the economic benefit of the developed joint. The progress of this research and development project will be shown based on testing for each stage of development and detailed analysis of failure modes with diagrams and pictures with the goal to achieve a more effective way of joining honeycomb panels.

Book excerpt: The Fourth Conference on Fibrous Composites in Structural Design was a successor to the First-to-Third Conferences on Fibrous Composites in Flight Vehicle Design sponsored by the Air Force (First and Second Conferences, September 1973 and May 1974) and by NASA (Third Conference, November 1975) which were aimed at focusing national attention on flight vehicle applications of a new class of fiber reinforced materials, the advanced com posites, which afforded weight savings and other advantages which had not been previously available. The Fourth Conference, held at San Diego, California, 14-17 November 1978, was the fi rst of these conferences to be jointly sponsored by the Army, Navy and Ai r Force together with NASA, as well as being the first to give attention to non-aerospace applications of fiber reinforced composites. While the design technology for aerospace applications has reached a state of relative maturity, other areas of application such as mi litary bridging, flywheel energy storage systems, ship and surface vessel components and ground vehicle components are in an early stage of development, and it was an important objective to pinpoint where careful attention to structural design was needed in such applications to achfeve maximum structural performance payoff together with a high level of reliability and attractive economics.

This book was released on 2012-06-23 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue of the pressurized fuselages of transport aircraft is a significant problem all builders and users of aircraft have to cope with for reasons associated with assuring a sufficient lifetime and safety, and formulating adequate inspection procedures. These aspects are all addressed in various formal protocols for creating and maintaining airworthiness, including damage tolerance considerations. In most transport aircraft, fatigue occurs in lap joints, sometimes leading to circumstances that threaten safety in critical ways. The problem of fatigue of lap joints has been considerably enlarged by the goal of extending aircraft lifetimes. Fatigue of riveted lap joints between aluminium alloy sheets, typical of the pressurized aircraft fuselage, is the major topic of the present book. The richly illustrated and well-structured chapters treat subjects such as: structural design solutions and loading conditions for fuselage skin joints; relevance of laboratory test results for simple lap joint specimens to riveted joints in a real structure; effect of various production and design related variables on the riveted joint fatigue behaviour; analytical and experimental results on load transmission in mechanically fastened lap joints; theoretical and experimental analysis of secondary bending and its implications for riveted joint fatigue performance; nucleation and shape development of fatigue cracks in riveted longitudinal lap joints; overview of experimental investigations into the multi-site damage for full scale fuselage panels and riveted lap joint specimens; fatigue crack growth and fatigue life prediction methodology for riveted lap joints; residual strength predictions for riveted lap joints in a fuselage structure. The major issues of each chapter are recapitulated in the last section.

The modelling of Machining Operations has become very widespread today, with many researchers developing models with which to predict metal-cutting performance. The aim here is to provide an answer to the challenges presented by the machining industry, which is presently facing very tight economical and environmental constraints. The collection of over 100 peer-reviewed papers covers twelve research topics, including: Analytical and Numerical Modelling; Cutting Fundamentals: Input Parameters; Cutting Fundamentals: Experimental Validation; Surface Integrity; Surface Topography; Tool Wear and Tool Life; Dynamics and Stability; High-Speed Machining and 5-Axes Machining; Abrasive Machining; Ultra-Precision and Micromachining; Computer-Aided Manufacturing (CAM); Experimental: Non-Conventional Machining. This work will thus constitute an invaluable handbook on the subject.

Available in PDF, EPUB and Kindle. Book excerpt: Honeycomb Technology is a guide to honeycomb cores and honeycomb sandwich panels, from the manufacturing methods by which they are produced, to the different types of design, applications for usage and methods of testing the materials. It explains the different types of honeycomb cores available and provides tabulated data of their properties. The author has been involved in the testing and design of honeycomb cores and sandwich panels for nearly 30 years. Honeycomb Technology reflects this by emphasizing a `hands-on' approach and discusses procedures for designing sandwich panels, explaining the necessary equations. Also included is a section on how to design honeycomb energy absorbers and one full chapter discussing honeycomb core and sandwich panel testing. Honeycomb Technology will be of interest to engineers in the aircraft, aerospace and building industries. It will also be of great use to engineering students interested in basic sandwich panel design.
