N2 - Based on the theoretical solution of stress singularity order, the corresponding stress intensity factors for a one or two-bonded wedge, under mechanical or thermal load, is determined using the finite element approach. The r-λ (λ is real or complex) and ln(r) stress singularity types are the major concern. For a wedge with two singularity orders, a modified least square method is proposed. Good agreement was observed when analytical results compared to experimental results. In the case that λ is complex, the numerical errors in calculating the angular functions expressed in the stress terms should be carefully examined.
