Abstract

Abstract

The problem of a Griffith crack in an unbounded orthotr opic functionally graded material subjected to antiplane shear impact was studied.The shear moduli in two directions of the functionally graded material were assumed to vary proportionately as definite gradient.By using integral transforms and dualimtegral equations,the local dynamic stress field was obtained.The results of dynamic stress intensity factor show that increasing shear moduli's gradient of FGM or increasing the shear modulus in direction perpendicular to crack surface can restrain the magnitude of dynamic stress intensity factor.
