โœฆ Synopsis

The steady state thermal stress intensity factors (TSIF'S) are analysed for hypocycloid, symmetric airfoil and symmetric lip type rigid cusp cracks embedded in infinite elastic solids, using BogdanotTs complex variable approach in plane thermoelasticity. Two thermal conditions are considered, one with an uniform heat flow disturbed by an insulated rigid cusp crack and the other with an uniform heat flow disturbed by a rigid cusp crack with fixed boundary temperature. The tendencies of TSIF's for rigid cusp cracks are somewhat different from those of traction free cusp cracks. However, if K = -1, the nondimensional&d TSIF's for rigid cusp cracks become those of traction free cusp cracks like the tendencies of the SIP's under mechanical loading conditions. The thermal stress and displacement components of a rigid circular inclusion of radius & are derived from the results of a rigid hypocycloid crack.

The boundary element method is applied to determine thermal stress intensity factors for a cusp crack in a transient state. In the steady temperature field, numerical values of thermal stress intensity factors for a Griffith crack and a symmetric lip cusp crack in a finite body are in good agreement
