FinEtoolsDeforLinear: Linear stress analysis application

FinEtools is a package for basic operations on finite element meshes. FinEtoolsDeforLinear is a package using FinEtools to solve linear stress analysis problems. Included is statics and dynamics (modal analysis, steady-state vibration).

News

• 05/27/2024: Remove unsupported functions. Adjust to FinEtools 8.
• 04/25/2024: Add utilities for split of isotropic elastic moduli.

Tutorials

There are a number of tutorials explaining the use of this package. Check out the index. The tutorials themselves can be executed as follows:

• Download the package or clone it.

git clone https://github.com/PetrKryslUCSD/FinEtoolsDeforLinear.jl.git

• Change into the tutorials folder: cd .\FinEtoolsDeforLinear.jl\tutorials.
• Start Julia: julia.
• Activate the environment:

using Pkg; Pkg.activate("."); Pkg.instantiate();

• Execute the desired tutorial. Here name.jl is the name of the tutorial file:

include("name.jl")

Examples

Many examples of solving for static and dynamic stress response with continuum FE models are available. Begin with changing your working directory to the examples folder. Activate and instantiate the examples environment.

using Pkg
Pkg.activate(".")
Pkg.instantiate()

There are a number of examples covering statics and dynamics. The examples may be executed as described in the conceptual guide to FinEtools.
