Abstract: The analysis of elastoplastic structures under a combination of static and dynamic loads is examined. It is shown that under the hypothesis of a ductile behavior, progressive distortion is the ...

Abstract: A method is presented to 1) account for ductility effects in the response of one degree of freedom systems by means of evaluating the frequency shift and additional damping; 2) evaluate the ...

Abstract: The three-dimensional nonlinear code PAULA is described; its finite element library makes it particularly useful for analysis of pipes. The problem of pipe whip is dealt with in some detail. ...
