# Overview

The key to structural scale applications is employing the "best" numerical method for the application. Typically, for solid mechanics, finite element methods are employed and used mostly for the engineering applications described in this CyberInfrastructure.

# Tutorials

Below are several codes that are used for simulating events at the Structural Scale.

CALCULIX[3]

COMSOL

EPIC ^{[1]}

The structural scale information essentially requires the constitutive model that is received from the macroscale. Although common practice finite element analysis does not include heterogeneities from microstructures, defects, and inclusions within the mesh related to the constitutive model, the MSU plasticity-damage 1.0 model allows the incorporation of such materials science information. The quantities that can be included in this version of the constitutive model are the grain size, particle size and volume fraction of particles, pore size and volume fraction or pores (porosity level), nearest neighbor distances of pores and particles. Hence, each element in the finite element mesh would have a different value for each of the quantities and hence the strength and ductility of the material in those domains. Several examples that show that by not using the heterogenous distributions of microstructures, defects, and inclusions include the redesign of a Cadillac control arm ^{[2]}, the Corvette engine cradle ^{[3]}, and a powder metal steel engine bearing cap ^{[4]}.

Some examples of using different finite element simulations with associated input decks using our MSU plasticity-damage 1.0 can be garnered from the following locations:

- Cadillac control arm (ABAQUS-Implicit)
^{[2]} - Corvette cradle (ABAQUS-Implicit)
- Dodge Neon crash (LS-Dyna)
- Forming of aluminum plate (ABAQUS-Implicit)
- Crush of aluminum tube (ABAQUS-Explicit)
- Axial Crushing of Multi-Cell Multi-Corner Tubes (LS-Dyna)
