Abaq_Mech_001 Mechanical Analysis Introduction
Contents
This example is provides a simple introduction to performing 2-D mechanical analysis using an explicit dynamic solver. Both dynamic and quasi-static cases are considered, and the methodology for obtaining quasi-static solutions using an explicit solver is demonstrated. Specific issues considered are:
1Problem set up for elastic simulation; i.e. material, prescribing displacement (support_data), surface loading, etc.
2Defining solution parameters.
3Obtaining steady state solutions using an explicit dynamic solver; i.e.
(a) Defining appropriate load curves
(b) Damping
(c) Monitoring the solution using high definition history
The problem consists of a 10m high by 1m wide elastic sandstone column. Uniaxial deformation is enforced by prescribing the horizontal displacement of the column sides and a 10 MPa surface load is applied to the top of the column. As an explicit dynamic solver is used the solution is time dependent and the surface load is prescribed with a time curve that defines its magnitude as a function of time. Several different time curves are considered including a linear ramp, S-Curve and an instantaneous load.
The data file and geometry definition are described in Case 1A Base Case Description.
