複合材料積層板の有限要素法解析のための境界条件処理法

抄録

This paper presents two boundary techniques which are useful for FEM analysis of composite laminates. One is a rotational symmetric boundary technique and the other is a quasi three-dimensional boundary technique. The use of the rotational symmetric boundary technique allows a smaller FEM model. With the use of the quasi three-dimensional boundary technique, quasi three-dimensional analysis of composite laminates can be performed on the conventional 3-D FEM program. These techniques can readily be adopted to FEM programs.
