Dynamic Analyses of Homalite-100 and Polycarbonate Modified Compact-Tension Specimens.

摘要

The fracture dynamic and crack arrest responses of modified compact tension specimen (M-CT) machined from Homalite-100 and polycarbonate sheets were studied by dynamic photoelasticity, dynamic finite element analysis and streaking photography. In contrast to the results of a previous study involving a mild steel M-CT specimen, substantial dynamic effects were observed during crack propagation in the Homalite-100 and polycarbonate M-CT specimens.
