    How to get uniform tension in a rail using dynamic/explicit analysis?

    Hello everyone, I’m working on a 3D simulation of a railroad track in ABAQUS using a dynamic/explicit analysis to investigate the longitudinal behavior of the rail. My model consists of multiple steps. In the first step, I apply a tensile force at one end of the rail, while the opposite end is...

    Defining multiple interaction in abaquss

    Hello all, I was wondering if there is any quick way to define contact-to-contact interactions in dynamic-explicit analysis for multiple surfaces and varying interaction properties. Thanks for your help.

    Contact Interaction and Gravity

    Hello guys, I'd really appreciate it if you answer my questions. 1- Is it necessary to have gravity load to activate contact interaction (to simulate friction) between two components? 2- What should be g (acceleration due to gravity) unit to be consistent with kips for force and inch for...

    Changing the slip interface by loading rate

    Hi everyone, I am currently working on the modeling of the railroad track. In my model, I have simulated the rail and the crossties by beam elements and used connectors to add longitudinal elastic and friction elements. The rail is pushed by a concentrated force in axial direction. I am...

    Slip in the rigid railroad track - ABAQUS model

    Hello everyone, I am currently working on a 3D FE model in ABAQUS, focusing on simulating thermal force resulting in a rail break which generates a gap in the rail. Model description: This model applies a compressive load in the longitudinal direction, aligned with the rail length, equivalent...
