Question

Which of the following statements is correct?

(a) Stiffness coefficient value for numerical solution is less than the value of exact solution

(b) Stiffness coefficient value for numerical solution is greater than the value of exact solution

(c) Stiffness coefficient value for numerical solutions is equal to the value of exact solution

(d) Stiffness coefficient value for numerical solutions is twice the value of exact solution

I got this question by my college director while I was bunking the class.

My question comes from Beams and Frames topic in division Beams and Frames of Finite Element Method

Answer 1

The correct option is (b) Stiffness coefficient value for numerical solution is greater than the value of exact solution

For explanation: The stiffness coefficient value for numerical solution is greater than the value of exact solutions. This yields the displacement value in numerical solution lower as compared to the value of exact solution.
