Plastic Collapse Modes of Truss Structures under Complex Loading Cycles

Chúng tôi vui mừng thông báo rằng GS. Phạm Đức Chính và các đồng nghiệp gần đây đã xuất bản công trình của họ có tựa đề " Plastic Collapse Modes of Truss Structures under Complex Loading Cycles" trên tạp chí Journal of Engineering Mechanics

Tóm tắt:

The kinematic plastic limit, unified shakedown criteria, and reduced kinematic formulation have been utilized to study the plastic collapse modes of truss structures subjected to complex loading cycles. The development from a series of local alternating plastic failures toward the global instantaneous or incremental collapse of the structures with increasing load ranges has been identified. The finite element method and optimization techniques are implemented to effectively solve the resulting mathematical programming problems, with illustrative examples and explanations
