This paper presents a LDU decomposition method of the stiffness submatrices for developing a microcomputer/personal computer-aided finite element method. The LDU method needs to use the computer disk memory equipment such as floppy and hard disks to store the data obtained. The finite element method (FEM) using the LDU method is applicable to an analysis of a three-dimensional elastic block under tension. This FEM is available for an analysis of structures of a large-size matrix required for a memory capacity larger than that of the machine itself. This LDU method also contributes to the decrease of memory capacity in the conventional FEM. Therefore, the LDU method is effective for a microcomputer/personal computer-aided FEM.
