有限要素法による平面張力場解析 : 剛性変化法を用いた一解析手法

抄録

The object of this paper is to make sure of availability for the numerical approximate procedure developed in our privious paper and to show the characteristics of the plane tension field using two models of simple plane configuration. The manipulation of elastic coeffcients is of important on the procedure because it is based on finite element techniques with variable stiffness. Therefore, this manipulation is elucidated to the case of not only isotropic materials but also anisotropic in detail. The procedure is then applied to the case of (1) a flat rectangular sheet subject to shear and tension in various directions and (2) a flat rectangular sheet subject to a force in one direction. The obtained numerical results are compared with the analytical solutions existing studies of the classical theory and numerical results that depend on another procedures using finite element techniques. Numerical results are favorably consistent with theorical values.
