Thermodynamic methods have been used to related material quantities to the crack driving force for material that is fracture toughened by a martensitic transformation. The material quantities are typically the coefficient of thermal expansion and the enthalpy for the martensitic phase transformation. A continuous dislocation distribution, with a dislocation free zone, at the tip of shielded Griffith crack was solved. Experimental comparison with the solution suggests that dislocation nucleation at the crack tip is important.
