Experimental measurements reveal that the buckling occurs earlier ---at lower compressive strains--- than expected from theoretical predictions. This paper shows that if rubber is modeled as being bimodular, and specifically, as being stiffer in compression than in tension, then flexure bifurcation happens indeed at lower levels of compressive strain than predicted by previous investigations (these included taking into account finite size effects, compressibi","authors_text":"Jerry G.
