WebBoundary conditions applied during an explicit dynamic response step should use appropriate amplitude references to define the time variation. If boundary conditions are … WebFor example, the time history of a displacement can be defined for a direct integration dynamic analysis step by an amplitude variation; in this case ABAQUS must compute the corresponding velocity and acceleration. ...

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.

WebApr 1, 2024 · The fluid dynamics of a bubble collapsing near an elastic or viscoelastic material is coupled with the mechanical response of the material. We apply a multiphase fluid–solid coupled computational model to simulate the collapse of an air bubble in water induced by an ultrasound shock wave, near different types of materials including metals … WebThe time dependence of the error is included by assuming that the amplitude of error is a function of time. Often the assumption is made that the error grows or decays exponentially with time, but this is not necessary for the stability analysis.

WebJul 26, 2024 · This is analysed using both Abaqus/Standard, and Abaqus/Explicit. In Abaqus/Standard, a step time of 1 s is used. In Abaqus/Explicit, either a step time of 1 s or a step time of 0.1 s is used. We will take a look at whether a solution is found, the time needed to obtain the solution, the deformed shape and the reaction force.
