buckling analysis of pipeline under external pressure
The buckling pressure of a uniform pipe under external pressure, can be evaluted by the linear analtical equation:
I use abaqus to simulate this problem. I tried for different pipe length and boundray conditions, the buckling pressure varies a lot, and even larger than the linear analytical results. Does anyone know how long do I need to build for the model and how to set up the boundray conditions. Many thanks.

Abaqus composite material shell interlaminar stress recovery
How do I recover the interlaminar stress/stresses 13, 23, or xz, yz for a composite laminate when using shell elements in Abaqus?
What type of elements should I use?
Fatigue analysis in ANSYS
RCC modeling in abaqus
It is necessray to define tension stiffening parameters in RCC model.
Evading the strength-ductility trade-off dilemma in steel through gradient hierarchical nanotwins
It is a long-standing goal in metallurgy to enhance the strength of materials without sacrificing ductility. In a recent article in Nature Communications, we reported an effective way to evade the strength-ductility trade-off dilemma in twin-induced plasticity steel.
