Abstract

Thermally loaded penny-shaped cracks in thermopiezoelectric materials are investigated in this paper. The analytical solutions for the penny-shaped cracks subjected to uniform temperature and steady heat flow are discussed. Comparisons are made between the stress-intensity factors derived by the analytical solutions and the numerical results using different finite element techniques.
