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. Reply To This Thread 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.

WebIn cases when the loads need to be maintained at the same values as in the original analysis, you can prescribe a constant (step function) amplitude variation for the analysis step (see Prescribing nondefault amplitude variations ) to apply the loads instantaneously at the start of the step and hold them for the duration of the step. 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
