文摘Deformation of mild steel plate with linear crocks due to horizontal compression is investigated by the use of 2-D FEM （two-dimensional finite element method） in the case of plane strain. The compound plate has a notch at the upper surface, which links to oblique downward initial defects. The compound plate roughly models the oceanic plate （Plate l） sinking under the continental plate （Plate 2） near the trough or trench in Japan. A horizontal compression is exerted at the left side of Plate 1. The deformation of the compound plate shows that the notch and upper surface of Plate 2 subside if a downward tension is added to the right side of Plate 1.
