... ABSTRACT This paper presents an elastoplastic soil model considering the principal stress rotation (PSR), which occurs in many geotechnical engineering problems such as in offshore foundations under wave loading. The model is developed on the basis of a well-established kinematic hardening...

... the plastic deformation of the HAZ, resulting in the large maximum principal stress ahead of the notch tip and a plastic strain concentration at the notch tip in the HAZ. It is found that the cleavage fracture of welded joints with strength mismatching obeys a critical tensile stress criterion. By using...

Influences of such factors as coefficient of intermediate principal stress and orientation of principal stress on strength and deformation behavior are examined on the basis of monotonic shear tests. The variation patterns used in cyclic shear tests are able to reproduce the stress conditions in seabed under...
