TLDR
In this article, a simple direct technique to determine a broad set of elastic moduli is presented based on compression testing of a prism sample, which is used to measure the full-field deformations that allow the determination of Young's moduli and all six Poisson's ratios for the three orthogonal directions based on a single sample.About:

Dong Chang Park,Dai Gil Lee +1 more
TL;DR: In this article, the effects of lay-up angles and specimen thickness of woven composites on TTCS were investigated for the efficient design of carbon-phenolic woven composite bearings, and it was found that the TTCS of the woven composite is much dependent on the stacking sequence rather than composite thickness.
