Abstract

In this paper, the design of cruciform shaped, planar biaxial loading specimens using finite element analysis, mechanical testing, and digital image correlation is discussed. The specimens were designed to be capable of arbitrary combinations of tension and compression loading. Digital image correlation results from uniaxial tension tests of first-generation specimen infer key design attributes of second-generation specimen. Finite element results are compared with a plane stress analytical formulation and differences between the two are attributed to stress concentration fields originating at the intersection of specimen arms. These results motivate a parametric finite element geometry optimization of second-generation specimen.
