Experimental observation and FEM analysis of initial fractures in quasi-isotropic CFRP laminates subjected to compressive loading

In this study, the mechanisms governing compressive strength in quasi-isotropic carbon-fiber reinforced-plastic laminates were clarified to gain an understanding of the results of non-hole compression tests. Synchronized observations of both sides of specimens provided insights into the locations of initial fractures in the width directions of the specimens. We also observed the areas surrounding the initial fractures in detail and found that...
