Alastract-The well-known equation of caustics about crack tips in experimental fracture mechanics is usually expressed in the form of two equations for the Cartesian coordinates (x, y) with a parameter (an appropriate polar angle playing the role of this parameter). Here we derive the equivalent uni
## Abstract This paper is directed towards finite element computation of fracture parameters in functionally graded material (FGM) assemblages of arbitrary geometry with stationary cracks. Graded finite elements are developed where the elastic moduli are smooth functions of spatial coβordinates whi
