| Abstract: | A solving procedure for the analysis of bearing elastoplastic contact problems
and the determinrtion of shakedown limit load under simple cyclic loading is
presened in this paper.Based on the flexbility matrices method described in1],
an incremental method is suggested to analyse elastoplastic contact and shakedown
This method needs less computational time to determine the contact area,pressure
distribution,and stress distribution,it is also shown to yield accurate results
and fit to analyse contsct problems with muti-body o(?)mutiple contact surface. |
