Abstract
The problem of a penny-shaped crack subjected to symmetric uniform heat flux in an infinite transversely isotropic magneto-electro-thermo-elastic medium is investigated. The exact solution in the full space is in terms of line integrals and the exact solution in the crack plane also is obtained. Although we start our derivations with magneto-electro-thermo-elastic, the solution presented in this paper is also applicable for linear transversely isotropic thermopiezoelectric, thermomagnetoelastic,thermoelastic materials (see Appendix E). The solution in the crack plane, which shows a great agreement with the solution for a transversely isotropic medium obtained by Tsai (1983), indicates that σx,σy,Dx,Dy,Bx, and By along the crack rim are of the same singularity of the normal stress or its equivalent quantities. To illustrate how the applied symmetric heat fluxes affect the whole fields, a numerical example is also given.
