This book was released on 1982 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this report is to disseminate experimental data of matrix-dominated time-dependent deformation and time-dependent damage in graphite-epoxy composite. The composite specimens were + or - 45 T300/5208 laminates tested in tension with complete instrumentation for stress, strain, and time recordings. Experimental data was recorded and archived in digital form. Polynomial series are fitted to the experimental data for compilation, dissemination and future retrieval. Data presented herein is accessible to the technical community at large for correlation and the formulation of theory from diverse perspectives, and to meet different goals in fundamental research and engineering applications.

This book was released on 1983 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this report is to disseminate experimental data of matrix-dominated time-dependent deformation and time-dependent damage in graphite-epoxy composite. The composite specimens were + or - 45 T300/5208 laminates tested in tension with complete instrumentation for stress, strain, and time recordings. Experimental data was recorded and archived in digital form. Noises in the data were minimized by digital elimination of the wild points in the excitation voltage and by a digital valuable low pass frequency filter with the cut-off frequency matched to the expected materials response. The data were presented both graphically and numerically. ...

Download or read book Mechanism Based Failure Laws for Graphite/Epoxy Composites written by and published by . This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A significant progress has been made towards achieving the overall goal of developing mechanism-based failure laws for graphite/epoxy laminate under biaxial compression. Microstructural-level mechanisms have been largely uncovered using examination of load-interrupted specimens, including the strength data under different materials axes orientations and in-plane biaxiality ratios. Mechanism-based failure laws for uniaxial compression have also been developed, including a fracture mechanics-based predictive crack density model. New and unusual size effects related to modulus were uncovered, and so were the observations that seem to indicate fiver microbuckling mechanism to be simply end loading related.

Available in PDF, EPUB and Kindle. Book excerpt: This report reviews the most important studies undertaken of the compressive failure mechanisms encountered in modern composite materials. It considers first the behaviour of unidirectional laminates, followed by unnotched and notched multidirectional structures. It then considers existing theoretical models. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database provides useful references for further reading.

Download or read book Splitting Initiation and Propagation in Flawed Unidirectional Graphite/epoxy Composites Under Tension-tension Cyclic Loading written by Mahmoud Hatem M. Helmi Daken and published by . This book was released on 1983 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: Damage by two distinct mechanisms is observed when flawed unidirectional graphite/epoxy composite specimens are monotonically loaded in tension along the fiber direction. The first mechanism is splitting damage i.e. the initiation of cracks at.the flaw tips that subsequently propagate in the matrix, parallel to the fibers, and towards the ends of specimen. This process divides the specimen into two outer load-carrying regions and a central load-free one whose width is equal to the flaw size. The second mechanism is the ultimate specimen failure by fiber breakage along planes normal to load direction and adjacent to the gripped ends. The initiation and propagation of splits under tension-tension cyclic loading were experimentally investigated. Ninety uni-directional [0]8 specimens with slits or holes of sizes 1/8", 1/4", and 3/8" were cyclically loaded to 80%, 70%, and 60% of their static splitting stress. The stress ratio of the load cycle was maintained at a nominal value of R[alpha] = 0.1 while cycling frequency was changed according to stress amplitude so as to keep a constant loading rate in all the tests. It was found that crack length varies with the natural logarithm of cycles endured in a linear fashion. The intercept of this line depends on flaw type, flaw size, and stress level while its slope depends only on flaw size and stress level. The functional forms of these dependencies were derived using multiple linear regression analysis of test data.
