Which of the following is not a method for calculation of the stiffness matrix?
A)The minimum potential energy principle
B)Galerkin's principle
C)Weighted residual method
D)Inverse matrix method

Question

Quizplus · Accepted Answer

The stiffness matrix in structural analysis and finite element analysis is calculated using principles that relate physical behavior to matrix operations, such as the minimum potential energy principle, Galerkin's principle, and the weighted residual method. These methods are based on physical principles and mathematical formulations that directly relate to the stiffness of materials and structures. The inverse matrix method, however, is a mathematical procedure used for solving systems of linear equations and does not directly calculate the stiffness matrix. It might be used in the context of solving for displacements or forces once the stiffness matrix is known, but it is not a method for calculating the stiffness matrix itself.
