Give relation between stress strain and internal energy density.
Relation between strain energy density and its complementary?
σε=U_{o}+C_{o}
Relationship between Complementary Strain energy density, stress and strain.
Give Hooke's law for 3-D
In 3-D it asserts that each of the stress components is a linear function of the components of the strain tensor.
What do you mean by anisotropic material?
Materials that exhibit stress-strain relationship as given by the Hooke's law in 3-D involving a number of independent elastic coefficients are said to be anisotropic.
How many elastic coefficients are there in general anisotropic linear materials?
21
Give the strain energy density of a general anisotropic material.
