MECHANISM ANALYSIS OF IMPACT PERFORMANCE FOR TUBULAR T-JOINT

With the development of tubular structure and the high frequency of impact accident, the study of impact performance for tubular T-joint becomes an fertile domain in the world. The theory model for members was established by FEA software ABAQUS in this paper, and the time history curve of impact force was calculated, and the analysis results were agreed well with the experiment results. On the base of analyzing mechanism for tubular T-joint under impact loading, the difference performance between under impact loading and under static loading was clarified, and the development of deformation was simulated, and the failure model and reaction between hammer and tubular T-joint were determined.
