Hi,
I am running a simulation in ABAQUS of the helical buckling of concentric tubes. Initially, I was conducting a static analysis with automatic stabilization.
Due to the high nonlinearity, I opted for a quasi-static implicit dynamic analysis. Therefore, Abaqus requires defining the material...
Hello, everyone.
I'm modeling the contact between two concentric tubes in ABAQUS. The inner tube is elastic, while the outer one is rigid. I used PIPE31 and ITT31 elements. The inner tube is under buckling.
First, I obtain the buckling modes to introduce the imperfections in the structure...
I am attempting to simulate the buckling problem of two concentric tubes in Abaqus, with the larger diameter tube being rigid.
To simulate contact, I have used the following conditions:
- general contact, all with self, type edge to edge, radial direction
The post-buckling analysis is...
Hello, everyone.
I'm trying to model the contact between two concentric tubes in ABAQUS. The inner tube is elastic, while the outer one is rigid. I used PIPE31 and ITT31 elements, created a rigid surface for the outer tube, and applied hard contact. However, the model does not converge, and...
