Question

We can obtain same assembly procedure by Stiffness matrix method and _______

(a) Potential energy method

(b) Rayleigh method

(c) Galerkin approach

(d) Vector method

I had been asked this question by my college director while I was bunking the class.

I need to ask this question from One Dimensional Problems in chapter One Dimensional Problems of Finite Element Method

Answer 1

Right option is (c) Galerkin approach

The explanation is: Galerkin method provides powerful numerical solution to differential equations and modal analysis. Assembling procedure is same for both stiffness matrix method and galerkin approach method in Finite element modeling.
