VCAMS

Mon, 02 Aug 2021 00:00:00 +0000

VCAMS (Voxel-Based Computer-Aided Modeling of Complex Structures) is a free and open source software for creating complex FEA models using voxels.

This software allows for accurate, fast, and reproducible modelling and can be used and extended by anyone in accordance with the GNU AGPLv3 license.

Its main features are:

Powerful Library: The VCAMS library is simple but powerful, allowing for easy scripting which makes the results highly reproducible. Also, the scripts can be archived and shared with others.
Simple GUI: The VCAMS GUI is a simple but elegant graphical user interface that allows for easy creation of some of the more widely used structures.
Fast: VCAMS is very fast. It can create a model consisting of one million elements in less than a second!
Thorough Documentation: There are in-depth articles about all aspects of VCAMS in the online documentation.
Free and Open Source: VCAMS and its source code are provided free of charge under the GNU AGPLv3 license. You can download the source code and the executables on the project’s GitHub page.

Numerical Modeling of Interphase in Dual-Phase (DP) Steels

Thu, 22 Sep 2016 00:00:00 +0000

Nano-Hardness experiments have shown that in dual-phase (DP) steels, the transition between the hard and soft phases is not sudden. This gradient of mechanical properties can be explained by existence of transformation-induced geometrically necessary dislocations (GND) created during manufacturing of the steel.

In this project, an in-house Matlab code was used to create-two phase RVEs from microscopy images. The resulting structure is then processed to generate an interphase between the two phases in which each element is assigned a distance to each phase. Then, different interpolation functions are used for simulating the change in hardness observed in the experiments.
