Abstract

Explicit integration of stiffness matrix elements is generally applied in derivation of simple element matrices because of the tedious manual calculation needed when complex governing equations or interpolation function of high orders are involved. This work at derivation of element stiffness matrix of elastic axisymmetric circular plate with uniform thickness by explicit integration method and applying it in solving several problems under different types of loading and boundary conditions. Comparison between to finite element solutions and those obtained from corresponding theoretical equations showed good agreement.
