25) Referring to Fig. , see Timoshenko and Goodier, 1982). 30) which applies to Cartesian coordinates, as well as to polar coordinates as demonstrated in Chapter 1. 6 RATE OF DEFORMATION For later hypoelasticity discussion, the incremental forms of stress and strain in formulating constitutive law are introduced here. For such cases, the rate of deformation is needed. 31) dv = L

124), the procedure can easily be modified to cylindrical coordinate. That is, both of them remain valid for cylindrical coordinates. 124) with appropriate boundary conditions. 124) would be the homogenous solution for the biharmonic equation plus the particular solution, which depends on the form of the body force potential V. We first consider the homogeneous solution. 130) R V II  f ¦[ A r n n 2  B nr  n  C n r n  D n r 2 n]( E n cos nI  F n sin nI ) n 2 where R is an arbitrary constant to normalize r.

For anisotropic solids, the equation of equilibrium will be much more complicated when it is written in terms of displacements. 13 COMPATIBILITY EQUATION IN TERMS OF STRESS TENSOR Sometimes, it is more convenient to rewrite the compatibility in terms of stress tensor. 77) u where ei is the base vector of any Cartesian coordinate. 83) 1 Q 1 Q which was obtained by Beltrami in 1892 and by Michell in 1900. 14 STRAIN ENERGY DENSITY If a solid is purely elastic, it recovers all its deformation upon unloading.
