11. This shear is given by the off-diagonal elements of the stress tensor . 12. The stress tensor of the brittle material is 13. For non-Newtonian fluids, there are different stress tensor to the shear rate tensor. 14. These are the three eigenvalues of the stress tensor , which are called the principal stresses. 15. The first and third invariant are the trace and determinant respectively, of the stress tensor . 16. You must be meaning stress tensor . 17. This tensor may be expressed as the sum of the viscous stress tensor minus the hydrostatic pressure. 18. The Cauchy stress tensor obeys the tensor transformation law under a change in the system of coordinates. 19. From the balance of angular momentum, the symmetry of the Cauchy stress tensor can be demonstrated. 20. Is the Maxwell stress tensor , and " c " is the speed of light.
