! The program is mainly used to solve the two-dimensional plane stress elasticity problems (with thickness), the f90 debugging through. ! Contains the main STRESS and words program ELSTMX (KK), MODIFY, DCMPBD and SLVBD! Main program for basic input-output and maximum half bandwidth calculation, the overall stiffness matrix assembly calculated stress and strain values! Subroutine elstmx ( kk) calculate the stiffness coefficient matrix to generate a first kk element stiffness matrix k! subroutine MODIFY input node of concentration, the displacement boundary nodes, the overall stiffness matrix and nodal force and displacement array array modified! subroutine DEMPBD using Gaussian elimination element method for the semi-bandwidth matrix becomes upper triangular matrix! subroutine SLVBD overall matrix for the displacement vector DD back intercessions
