AN EXPERIMENTAL STUDY OF THE LARGE DEFORMATION OF PLASTIC HINGES

Recent applications of structural plasticity to areas such as vehicle crashworthiness has led to interest in the large deformation plastic collapse of general frames. Even when displacements are comparable to the original structural dimensions, the plasticity is confined to localized regions or "hinges". This paper reports an experimental study of the behavior of such hinges in thin walled structural members. Due to local deformation the load carrying capacity of the hinge significantly decreases at large rotations. In a companion paper (4) a structural constitutive theory is proposed to account for this behavior. Numerical data for this theory is obtained in the present paper. Finally test results are given for a large deformation combined loading test designed to validate the theory of (4). The experimental results are in good agreement with the theoretical predictions. /Author/TRRL/
