    Adams Flex

    Hello, I'm using AdamsFlex. I meshed the flexible body with Ansys and imported the .mnf file in Adams flex. The problem is that : The weight of the flexible body is 0.064kg in Ansys whereas its mass is 0.260Kg in Adams ! The correct mass is the first one. Units are specified in SI (MKS)in both...

    riks - critical load

    Hello, There is something that I don't understand about the determination of the critical buckling load. The method is : 1) Perform a linear analysis to have an idea of the critical load and its associated mode. 2) Introduce a perturbation in the geometry (*IMPERFECTION) 3) Perform a...

    logarithmic meshing

    Someone knows how to generate a meshing with a logarithmic bias along the length of a body ? I want to refine it. Thanks !

    linear buckling analysis versus preload frequency analysis

    Hello, There is something that I don't understand. A linear analysis of buckling (BUCKLE card) is solved by the research of the load for which the stiffness matrix become singular. Thus, an eigenvalue analysis with various preloads should be another way to verify the critical load. The value...

    buckling

    buckling I'm doing a non-linear analysis in order to perform buckling of a strip. One extremity is clamped. The second one is free and a load is applied. The linear buckling analysis was ok. For the non-linear one, using S4R5 elements, *STEP,NLGEOM,INC=500 *static,riks ... adding an...
