Compressive Failure of Open-Hole Carbon Composite Laminates

Abstract

The issue of how open-hole carbon composite laminates fail in compression is addressed in this paper. The author makes use of finite element analysis, coupled with SIFT and EFM, in order to predict failure of open-hole composite laminates. The results obtained from the simulations are then compared with experiments done by other researchers which are documented in papers and journals. Two methods of modeling, one based on micro-buckling and another based on compressive residual strength, i?? are used, and the two methods compared with experiments done by others to see which one gives better results. Using the i??i? method of analysis and modeling, the author also investigates two other concerns: mesh dependency of the finite element method and the effect of the stacking sequence.
