Card Set Information
Give relationships between variation of strain components with displacement variation.
What is the first law of thermodynamics?
The work performed on a mechanical system plus the net heat that flows into the system equals the increase in internal + kinetic energy of the system.
What are the assumptions used in introducing force quantities?
1.Static equilibrium δK=0
2.Adiabatic condition δH=0
Give the relationship between variation of internal energy density in terms of stress components and their variations?
is a function of what all variables?
Give relation between stress strain and internal energy density.
Relation between strain energy density and its complementary?
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?
Give the strain energy density of a general anisotropic material.
