The goal of the work surrounding Tahoe is the simulation of stresses and deformations for situations that cannot be treated by standard continuum simulation techniques. These situations include material fracture or failure, interfacial adhesion and debonding, shear banding, length-scale dependent elasticity and plasticity, and deformation in small-scale structures. Aside from a collection of standard finite elements, Tahoe includes meshfree simulation capability and particle methods. Tahoe includes a number of "cohesive" approaches for modeling fracture. These include both surface and bulk constitutive models that incorporate cohesive behavior. Tahoe is capable of performing static and transient dynamic coupled-physics analysis in two and three dimensions. Many capabilities support parallel execution. http://tahoe.cvs.sourceforge.net/viewvc/tahoe/guide.user/; http://tahoe.sourceforge.net/bb/; http://tahoe.sourceforge.net/wiki/index.php/Main_Page https://hdl.handle.net/11256/514 microMegas (mM) MicroMegas is a 3-D DDD (Discrete Dislocation Dynamics) simulation. MicroMegas (also known as 'mM') is an open source program for DD (Dislocation Dynamics) simulations originally developed at the 'Laboratoire d'Etude des Microstructures', CNRS-ONERA, France. mM is a free software under the terms of the GNU General Public License as published by the Free Software Foundation. Discrete dislocation dynamics (DDD) is a numerical tool used to model the plastic behavior of crystalline materials using the elastic theory of dislocations. DDD is the computational counterpart to in site TEM tests. MicroMegas is a legacy simulation code used to study the plasticity of mono-crystalline metals, based on the elasticity theory that models the dislocation interactions into an elastic continuum. In crystalline materials, plastic deformation may be explained by (i) twinning, (ii) martensic transformation or/and (iii) dislocation interactions. http://zig.onera.fr/mm_home_page/doc/Article_mM_2011.pdf; https://icme.hpc.msstate.edu/mediawiki/index.php/Code:_microMegas https://hdl.handle.net/11256/513 Ternary Ternary is a free energy visualization tool. Inspired by Craig Carter's Mathematica scripts for binary mixtures, it uses qhull to calculate the convex hull of the free energy curve, and visualizes the result including two-phase tie lines and three-phase triangles. For multiple phases, such as the situation to the right, visualizing their intersection is tricky, but the principle is the same: the convex hull gives the minimum energy surface. This consists of two libraries: libfreenergy and libgibbs, two example C-codes: ternary (output shown) and square, and a graphical user interface (GUI) called Ternary. The libfreenergy library computes free energies and their derivatives, and can be shared with phase field software, which uses free energies as a starting point. The RheoPlast project's ternary Cahn-Hilliard module uses libfreenergy to share free energy functions with Ternary. The libgibbs library includes the rest of the phase diagram isotherm calculation infrastructure.
