Abstract Magneto-electro-elastic composite with a penny-shaped crack is analyzed. The exact solution of temperature field based on non-Fourier heat conduction is derived by the method of standard separation of variables. The thermal stress, electrical displacement and magnetic induction in the transversely isotropic and axis-symmetric magneto-electro-elastic cylinder are evaluated by Hankel transform technique. The thermal stress, electrical displacement and magnetic induction intensity factors at the tip of penny-shaped crack are obtained by Abel type integral equation. The influence of the thermal relaxation time, crack length, characteristic length of materials and magneto-electro-thermo-elastic coupling on intensity factors are analyzed. Thermal shock resistance of MEE cylinder is evaluated by associating the stress based failure criterion and fracture mechanics based failure criterion.
