Application of an Eigenfunction Expansion Method in PlasticitySource: Journal of Applied Mechanics:;1974:;volume( 041 ):;issue: 002::page 448Author:T. Wierzbicki

Abstract: Possibilities of extending the eigenvalue expansion method to dynamic problems for plastic continua and structures are examined. A model of a pseudo strain rate sensitive material is introduced as an approximation to the concept of rigid-perfectly plastic material. A simple method is then developed which parallels the familiar elastic mode expansion technique but yet retains the main features of rigid-plastic behavior. The accuracy of the method is discussed and comparison with previous theories is made. An illustrative example is presented.
