Thermomechanical Simulation of Additive Manufacturing Processes

Abaqus/Standard offers a general framework for thermomechanical simulations that allows you to define appropriate boundary conditions, loads, interactions, constraints, and temperature-dependent material properties. This section provides an overview of special techniques that are available for, but not limited to, thermomechanical simulations of additive manufacturing processes.

A thermal-stress analysis of additive manufacturing processes:

  • allows exact specification in time and space of processing conditions, such as material deposition sequence, laser scan path, laser properties, and build environment;
  • allows precise control over the fidelity of solutions for different simulation needs;
  • can be followed by analyses of heat treatment applications, support removal, and/or mechanical performance tests, etc.; and
  • is usually more accurate but more computationally expensive than an eigenstrain analysis.
