Question

For quadrilateral with  2X2 integration gives _____ sets of stress values.

(a) One

(b) Two

(c) Three

(d) Four

This question was addressed to me in class test.

My enquiry is from Numerical Integration in division Two Dimensional Isoparametric Elements and Numerical Integration of Finite Element Method

Answer 1

Right answer is (d) Four

The best explanation: The stress applied to a material is the force per unit area applied to the material. The maximum stress a material can stand before it breaks is called the breaking stress or ultimate tensile stress. Tensile means the material is under tension. The forces acting on it are trying to stretch the material.
