Steady dynamic buckle propagation simulation of confined pipelines under external pressure by user defined elements in ABAQUS
2021
This paper simulates steady dynamic buckle propagation of confined linearly elastic pipelines under external pressure by developing a user-defined-element in Abaqus allowing the simulation of dynamic propagation through conventional static step. The simulation is separated into two parts: the static indenting step to deform a pipeline locally and the steady dynamic propagation step to obtain the relationship between the deformation profile and propagation speed.
