Abstract

The usage of cruciform specimen for planar biaxial coupon testing is evaluated using finite element analysis. Nine cruciform designs made up of a multidirectional laminate are simulated under a biaxial loading state to test the uniformity of the local stress state and the global strain state in the off-axis layer and on the surface of the biaxial zone respectively. The learnings from this analysis though valid for the current loading condition is a step towards finding a possible ‘one for all material configuration’ cruciform specimen design in the future, which in turn can simplify the task of sizing of the cruciform specimens made up of composite materials.
