Abstract

Corrugated structures have wide application in engineering.The corrugated structure is replaced by an orthotropic plate with equivalent stiffness properties in this paper.After equivalent stiffnesses are obtained, deflections and modals of simply supported orthotropic plates can be analyzed theoretically, which are compared with finite element solutions modeled with corrugated structures.Finally, it is clearly that corrugated structures can be replaced by an orthotropic plate whit equivalent stiffness in deflection and modal analysis.
