WebIt is a quasi-static analysis with a time period = 1. Two steps are defined in which the gravitational force is applied in the first step and a load is applied on a smaller area at the second step. I came up with time scaling =1e-6 such that the density increases 10 times in these problematic elements. WebOct 22, 2024 · Check amplitude definitions (if used). Remedy: Reduce the loading rate or reduce mass scaling. Multiple contact constraints on a node Reason: Typically this occurs when a surface is pinched between two bodies. can i clean my air purifier filter

Implicit vs explicit finite element analysis: when to use which?

WebBoundary conditions applied during an explicit dynamic response step should use appropriate amplitude references to define the time variation. If boundary conditions are … WebAn improved homotopy analysis method (IHAM) is proposed to solve the nonlinear differential equation, especially for the case when nonlinearity is strong in this paper. As an application, the method was used to derive explicit solutions to the rotation angle of a cantilever beam under point load at the free end.

WebIn an Abaqus/Standard dynamic or modal dynamic procedure, amplitude curves specified for TYPE = DISPLACEMENT or TYPE = VELOCITY will be smoothed automatically. In an Abaqus/Explicit analysis, the user must request that such amplitude curves are smoothed. For more information, see Amplitude Curves . BLOCKING WebAug 8, 2013 · yes, use a "tabular" amplitude 0,0,1,1 ; this will give you a ramp (if your time is 1) In explicit, it's sometimes better to use a "smooth step" amplitude to avoid high kinematic energy and inertial effects (and possible excessive element distortion), but this depends on your model & loads.

WebOct 30, 2024 · Using Smooth Step amplitude curve We could obtain a more accurate quasi-static solution by applying loads gradually. By default, Abaqus/Explicit loads are applied immediately and remain constant throughout the step. Instantaneous loading may induce the propagation of a stress wave through the model, producing undesired results. WebAmplitude references are passed into user subroutine VDLOAD in an Abaqus/Explicit analysis. Only the load magnitude is changed with time. Quantities such as the direction of an applied gravity load and the fluid surface level in hydrostatic pressure loading are not changed. CONSTANT RESULTANT

WebIn an Abaqus/Explicit analysis, the user must request that such amplitude curves are smoothed. For more information, see “Amplitude curves,” Section 33.1.2 of the Abaqus Analysis User's Manual.

WebTwo load steps in the HydroQus model were generated. The first step was prepared to apply the initial displacement, and the second was for viewing the free-decay motion. No boundary conditions were assigned to the second step of the HydroQus model; thus, the six degrees of freedom motion could develop freely without any constraints. 4.2.
