Three-Dimensional Finite Element Analysis of Antisymmetric Four-Point Shear Specimen
Keyword(s):
In this paper, the four-point shear (FPS) specimen is studied for different combinations of crack depth (a/W) and specimen thickness (t/W) to width ratios. Extensive 3D finite element analysis (FEA) has been carried out, and comprehensive solutions of fracture parameters produced. From the results of the finite element analysis, the size of the plastic zone is studied at various points through-thickness. Through these analyses, the effects of considering finite-thickness specimens are illustrated.
