Abstract The finite element method was used to solve the coupled elastic–plastic boundary value problem and transient hydrogen diffusion initial boundary value problem. Solutions were obtained at room temperature and under plane strain deformation in the neighborhood of a blunting crack tip under small scale yielding conditions and in the neighborhood of a rounded notch in a 4-point bend specimen. A discussion of the finite element results in conjunction with different mechanisms of hydrogen… CONTINUE READING
