Question

In axisymmetric problems, by using stress strain relation and strain displacement relation we can obtain an equation that is ____

(a) σ=DB̅q

(b) σ=D

(c) σ=Dε

(d) σ=Dε^0

This question was addressed to me by my college director while I was bunking the class.

Question is taken from Finite Element Modelling topic in division Axis Symmetric Solids Subjected to Axis Symmetric Loading of Finite Element Method

Answer 1

Correct choice is (c) σ=Dε

To explain I would say: The relationship between the stress and strain that a particular material displays is known as that particular material’s stress–strain curve. The strains give information about the deformation of material particles but, since they do not encompass translations and rotations, they do not give information about the precise location in space of particles.
