The entire procedure of the finite element method involves the following steps: The given body is subdivided into an equivalent system of finite elements. Suitable displacement function is chosen. Element […]
Calculation procedures for the modified Newton-Raphson method are the same as for the Newton-Raphson method, except the stiffnesses for the first cycle are held constant for each iterative cycle of […]
In a static or steady-state problem without substitution of a minimum number of prescribed displacements to prevent rigid body movements of the structure, it is impossible to solve this system, […]
The physical significance of the singular nature of the element stiffness matrix is found by reexamination that no displacement constraint whatever has been imposed on motion of the spring element; […]
Symmetry of the stiffness matrix is indicative of the fact that the body is linearly elastic and each displacement is related to the other by the same physical phenomenon.
The equilibrium of the nonlinear model is achieved when the force imbalance is zero or sufficiently small. This equilibrium is obtained by an iterative procedure that consists of steps at […]
