    Non linear fatigue simulation

    I wanted to do a fatigue analysis. The initial stresses I obtain is above the yield limit. There is non-linearity due to contacts and plasticity. I have few queries as below. Stress Based Approach For high cycle fatigue I am using a (S-N) approach because the linear stresses are below 70% of...

    Fatigue simulation

    Hello all, I have seen a case where while doing a fatigue calculation of an axle ball pin the load time history is divided into positive and negative signals. There is contact non linearity as well, since the ball pin will be in contact with an insert and will have a complex stress state...

    Increase in plastic strains after unloading

    Hello all I have a case in ABAQUS calculation where I applied the load on a bracket (bracket is attached to a frame, and bracket and frame are welded together), there is plastic deformation after loading on the frame. After unloading, the plastic strains are increasing on the frame. But as per...

    How to request sectional forces for shell elements in ABAQUS

    Hello all I would want to write the sectional forces in 2D shell elements of a specific section in my model. How do I request the same in ABAQUS. *SURFACE, NAME=sectional_forces_nodes, TYPE=NODE sectional_forces_nodes, 1. *SECTION PRINT, NAME= section_SF, SURFACE=...

    Early buckling of bracket

    Hello, I had a general question. I have a frame and a bracket, bracket is mounted onto the frame. Case - 1 When load is applied on the bracket, it buckles at 45 kN. Case - 2 I initialized plastic strains on the frame (not on the bracket) using *initial conditions, Now, when load is applied...

    Plastic strains as initial condition in ABAQUS causing reduction in strength

    Hello All In my ABAQUS simulation, I initialize the model with plastic strains and thickness data from forming simulation and use this data for buckling load simulation in ABAQUS. When I do the buckling load simulation, the model in which plastic strains and thickness data is initialized shows...
