This book was released on 1975 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental program was conducted to study the effects of foreign object damage (FOD) on the bending fatigue characteristics of a composite material, unidirectional boron/aluminum-6061. Fatigue curves were generated for a control group and each of four levels of FOD. The composite was further, characterized by static tensile and nondestructive tests. All tests were carried out at room temperature. A similar damage and fatigue experiment was done for a titanium alloy, Ti-6A1-4V, to provide baseline data with which to compare the composite. It was concluded that the composite suffers a greater percentage reduction in fatigue strength than does Ti-6A1-4V for a given impact energy.

Available in PDF, EPUB and Kindle. Book excerpt: The investigation was conducted to study the effects of foreign object damage on the residual tensile and tensile fatigue strength of a composite material, unidirectional boron-aluminum-6061. Curves were generated for various levels of tensile prestress during the ballistic impaction which related velocity of impact with the residual tensile strength of the specimens. The composite material was further characterized by tensile fatigue tests, radiography, and photography. A similar damage and fatigue analysis was done for Ti-6Al-4V to provide baseline data with which to compare the composite. All tests were carried out in lab air and at room temperature. It was concluded that for a given level of impact damage B/Al-6061 suffers much greater total loss and percentage loss of residual tensile strength than does Ti-6-4. Also, a fracture mechanics model fits the failure stress versus crack length data for B/Al-6061 resulting from hard-body impact. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This study investigated the effects of soft body impact damage on the residual tensile and axial fatigue strength of Boron-6061 Aluminum composite material. Unidirectional B-6061 Al specimens were impacted with room temperature vulcanizing rubber (RTV) spheres in a powder charge gun facility. Specimens were also impacted under five different tensile loads. Residual tensile strength versus impact velocity plots were generated for each prestress level. The composite was further characterized by axial fatigue and nondestructive tests. All tests were carried out at room temperature. A similar damage and residual strength analysis was done for Ti-6Al-4V to provide baseline data against which to compare the composite. It was concluded that Ti-6Al-4V is much more resistant to impact damage than unidirectional B-6061 Al. A fracture mechanic analysis is presented and a fracture mechanics model proposed for unidirectional B-6061 Al impacted specimens.

Available in PDF, EPUB and Kindle. Book excerpt: Fatigue damage mechanisms have been investigated using a series of tension fatigue tests on several laminates of boron/aluminum (6061-0). This study focuses on four aspects of the fatigue response. First, in laminates with 0-deg fibers on the outside, an analysis that identifies "shakedown" conditions is shown to predict the stress amplitude below which no fatigue damage accumulates. Second, a simple fatigue damage accumulation model which relates matrix fatigue cracking and the overall laminate properties is described. A model for the saturation damage stage development is presented. Third, data illustrate that identical laminates, tested in directions 90-deg apart (such that one layup has 90-deg outer plies and the other 0-deg), have different fatigue behaviors due to the stacking sequence. The 90-deg plies on the surface develop cracks earlier than predicted by shakedown. An attempt is made to explain this stacking sequence effect. Finally, variable load history effects on the fatigue damage response are investigated by simple tests. These tests reveal that for a given stress ratio the specimen seeks the saturation damage state for the largest stress range to which it is subjected. It also was found that little damage is generated by shifting a given stress range down, whereas significant damage may be created by shifting it upward.

Available in PDF, EPUB and Kindle. Book excerpt: The foreign-object damage problem associated with jet engines was investigated by impacting both titanium (6Al-4V) and boron-aluminum specimens with either steel or room-temperature vulcanizing rubber spheres to simulate the two principal types of ingested foreign objects. To simulate engine operating conditions, some specimens were impacted while under a tensile load. Results indicate that a prestressed composite suffers much greater damage than simple cantilevered specimens. Ti-6Al-4V exhibits excellent impact resistance, loosing only 10 percent of its ultimate tensile strength up to the highest prestresses and impact velocities. Composite specimens react much differently depending on the type of impactor. Steel spheres cause severe damage at very low impact velocities. Room-temperature vulcanizing rubber, on the other hand, causes little damage up to a velocity threshold. Above this point, specimen failure was observed at some prestresses upon impact. The residual tensile and low-cycle fatigue strength of both boron-aluminum and titanium was documented for various impacting velocities and prestresses. A fracture-mechanics analysis is presented which successfully predicts the effects of room-temperature vulcanizing rubber impact on boron-aluminum composites.
Book Synopsis Fatigue Damage in Boron-Aluminum by : AR. Bunsell
Download or read book Fatigue Damage in Boron-Aluminum written by AR. Bunsell and published by . This book was released on 1979 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fatigue behavior of three boron fiber reinforced aluminum alloys (1200, 6061.T6M, 2024.T4) has been examined in circular bending and the mechanisms which lead to their progressive deterioration studied. In B-1200, the broken fibers are isolated by crack growth in the matrix parallel to the fibers and originating at the fiber failures. In B-6061.T6M, the broken fibers initiate matrix cracks which are normal to the fibers and which pass around intact fibers without producing their failure. In B-2024.T4, a broken fiber can lead to the failure of the neighboring fibers because of load transfer by the matrix; when this failure is not immediate, it can occur because of matrix cyclic work hardening leading to an increase in transferred load. The matrix bridging two fibers subsequently fails in fatigue after their earlier failure.

Available in PDF, EPUB and Kindle. Book excerpt: This bibliography continues and updates previously issued reports by Battelle's Columbus Laboratories information centers on fibers, fiber-reinforced composites, as well as laminate, particulate, and eutectic composite materials. No organic matrix composites or fibers are included. This edition includes 2367 literature references published between January 1972 and September 1978. The references are arranged alphabetically according to author's last name or the name of the organization concerned and chronologically by year of publication. The subject categorization of this edition is similar to that used in the earlier bibliographies. References pertaining only to fibers are indexed as (1) general reviews; (2) growth, forming, or surface treatments; and/or (3) test methods and structural properties. Entries relating to composites are broadly indexed according to matrix materials and specifically by fiber materials. Composites are also indexed (at least once) in the following areas: (1) compatibility studies; (2) theory, analysis, micromechanics, and design; (3) testing and evaluation; (4) application; (5) general review articles; (6) fabrication; and (7) coatings. The report includes both an authors index and a subject index. (Author).
