The relationship between stress and strain can be visualised by plotting stress as a function of strain (Figure 1.7 in the text) The stress-strain (σ-ε) ratio, the ratio of the stress to the strain in that region for a particular load type, provides a numerical value of what?

Question

Quizplus · Accepted Answer

The stress-strain ratio provides a numerical value of the elastic modulus, which is a measure of the stiffness of the material. Therefore, the correct choice is C - the elastic modulus. A is incorrect because compliance modulus is the reciprocal of elastic modulus. B is incorrect because shear modulus is a measure of the material's resistance to deformation by shear stress. D is incorrect because compressive modulus is not a commonly used term in material science, and it is not related to stress-strain behavior.
