Abstract

Abstract

The anomalous response of elastic-plastic circular plate subjected to various rectangle and triangle impulse loadings is studied. The influences of various loading modes and loading areas on the counter-intuitive behavior of the plate are numerically analyzed in detail. The characteristics of the counter-intuitive behavior under different loadings are obtained. The relation between the number of the displacement peaks in the time-displacement curve and the loading range corresponding to the anomalous response is discovered. The results show that the minimum number of the successive counter-intuitive behaviors can be evaluated from the time-displacement curve corresponding to the first counter-intuitive behavior.
