Owing to the existence of distributed holes,it is difficult to solve the bending problemof perforated plates by the conventional finite element method.A homogenization-based method forthis problem is presented in this paper.As an example,the bending analysis of a circular perforatedplate with distributed step-wise cylindrical holes is made.The deflection and the fundamental frequen-cy obtained by present method are in good agreement with experimental data,this implies that themethod is effective.

Owing to the existence of distributed holes, it is difficult tosolve the bending problem of perforated plates by the conventionalfinite element method. A homogenization-based method for this problemis presented in this paper. As an example, the bending analysis of acircular perforated plate with distributed step-wise cylindricalholes is made. The deflection and the fundamental frequen- cyobtained by present method are in good agreement with experimentaldata, this implies that the method is effective.
