Ballistic penetration and fragmentation of brittle targets

The attached, to appear in I.J. Impact Engng., is an attempt to simplify such very complex calculations using an incubation time concept for defects coalescence, in the spirit of Tuler and Butcher and others.

By comparing the calculations and the experiments, it seems that the approach works nicely, produces realistic results, and most of all does not necessitate complex models with too many parameters of very sophisticated FE formulations.

 

Enjoy

Role of grain boundaries in determining strength and plastic deformation of yttria-stabilized tetragonal zirconia bicrystals

Mechanical properties of yttria-stabilized tetragonal zirconia (YSTZ) bicrystals under compressive loading are investigated by atomistic simulations. Previous studies on deformation of single-crystal YSTZ showed that some specific orientations promote dislocation emission, tetragonal to monoclinic phase transformation, or both. In this work, nanograins with different orientations are selectively combined to generate bicrystals with various grain boundaries (GBs).

Bio-based Self-healing Mortar: An Experimental and Numerical Study

Recent years have seen a lot of development in the field of self-healing materials. Our group at Delft University is working (for more than a decade) on development of self-healing concrete which uses bacterial spores embedded in the matrix to "heal" cracks. In recent years, the focus has shifted on development of numerical models as tools for development of these materials.

Postdoctoral position on: Inversion in nonlinear elastodynamics with application to the imaging of damaged media - CNRS & Aix-Marseille University, France

A one-year postdoctoral position is available at the Laboratory of Mechanics & Acoustics, CNRS & Aix-Marseille University, France.

 

This project focuses on the propagation of waves in damaged solids, which involves nonlinear phenomena. The proposal aims at studying the inverse problem of parameter identification from elastodynamic data to quantify the nonlinear properties of the propagation medium. The work will address the theoretical and numerical aspects of the problem.

Modification of GUI

I've using ANSYS APDL for my Master's Thesis. I'm working on crack propagation.

To do Crack path in ANSYS the initial GUI need to be modified as in the Images attached.

Anyone know about how to do this, please help me in modifying the GUI.

Awaiting your valuable comments.
