Abstract
This chapter discusses the J-integral evaluation for compact tension specimen. It presents the comparison of the J-integral evaluation by Rice's method to the one by the finiteelement method for the standard bend bar specimen (a/W=0.5). The result is that Rice's method gives the higher value than the finite element method by about 10%. There are three ways to evaluate the J-integral based on the result by the finite element method: J-integral is evaluated by equation using the strain energy obtained by the finite element method; J-integral is evaluated by equation using the strain energy and the complementary energy obtained by the finite element method; and J-integral is evaluated by calculating the difference of the strain energy ΔU, as J-integral is given by equation.
