The J-integral is commonly used to determine the resistance of plastically deformed structures to continued crack growth. This approach is only valid for monotonic loading and small crack growth; yet it is believed conservative for all general loadings. Another parameter, T∗ , has been formulated, which is theoretically valid under a wide range of conditions. These two plastic fracture criteria, a...... hiện toàn bộ
