    Elasto-plastic

    Thank you all for your more valuable information. Load for which the plastic strain has been developed is not a cyclic loading. This high stress is mainly due to the shrink fit pressure which is simulated by means of contact elements. The stress mainly get concentrated at the holes and at the...

    Elasto-plastic

    Thank you Gurmeet, Your explanation helped me to understand much better. As you said the material barely started to yield, is that indicates that component will fail. Or i need to study in detail whether this plastic region will grow futher, but this plastic strain is for my extreme load case...

    Elasto-plastic

    Hi all, I am doing elasto-plastic analysis using bi-linear material curve. I am new to this type of analysis and for the plasticity application. I have problem in interpreting with my results. In elastic analysis I got the von Mises stress of about 257MPa which is more than the yield limit of...

    Shrink fit + Inertial load

    Brain, Thanks and you are true. Although I have friction defined between the two cylinders it is not enough to hold them together when I apply the inertia load. With the slightly increased friction value now I could able to solve the problem with the inertia load in the axial direction. But...

    Shrink fit + Inertial load

    Hai, I used standard 3D surface to surface contact, also i have specified the CNOF for the shrink fit. For information, only the outer cylinder is constrained in all DOF. I am thinking the shrink fit contact pressure developed in the first sub step should hold the inner cylider with the outer...

    Shrink fit + Inertial load

    Hai, For quick understading: I simulating shrink fit between two cylinders and then i am applying inertia load to the model. I am facing convergence issue could any one can help me on this. To be more clear, my shrink fit step solves perfectly , then i use the restart option in Ansys, to...
