Finite Element Method

This paper presents an effective numerical approach for welding process
parameter optimization to minimize weld-induced distortion in
structures. A numerical optimization framework based on coupled Genetic
Algorithm (GA) and Finite Element Analysis (FEA) is developed and
implemented for a low and a high fidelity model. Classical weakly
coupled thermo-mechanical analysis with thermo-elasto-plastic
assumptions is carried out for distortion prediction of numerical
models. The search for optimum process parameters is executed by direct
integration of numerical models and GA-based optimization technique. The
developed framework automatically inserts the process parameters into
the simulation models, executes the FE-based welding simulations and

Dear Colleague,

this is to inform you that the research unit MUSAM "Multi-scale Analysis of Materials" (http://musam.imtlucca.it) at the IMT Institute for Advanced Studies Lucca (Italy) has opened 1 Post-doctoral Fellow position (1 year but renewable for a maximum of 3 years in total) on Computational mechanics applied to solar energy materials, related to the ERC Starting Grant CA2PVM
(http://musam.imtlucca.it/CA2PVM.html) and under my supervision.

This is a call of interest for a post-doc position (1 year renewable up to 3 years) at the IMT Institute for Advanced Studies Lucca, Italy (www.imtlucca.it), in the field of computational damage and fracture mechanics. The activities are in the framework of the ERC Starting Grant IDEAS "Multi-field and multi-scale Computational Approach to design and durability of Photovoltaic Modules" (Prof. Paggi, Principal Investigator).

For more details about the project, see:

Research Studentship (PhD) in Computational Material Science: the topic is computational nano mechanics and concurrent multiscale methods for composites under impact loading.

An excellent opportunity to work in a world leading team with privileged access to facilities that most researchers can only dream about.

Key Qualifications

 The project

This project aims at improving the efficiency of the manufacturing process of MEMS while decreasing the production cost by considering at the design stage the uncertainties in such a way that a range of the MEMS properties can be predicted for the manufactured products, which will be immune to factors that could adversely affect performance. This approach is called robust design and it is focused on achieving target reliability.

Job description: We are looking for a smart, dynamic, and highly motivated individual with a PhD to perform groundbreaking research in biomechanics with applications to ophthalmology.

Hi all,

I have a strange question that has puzzled me since last almost one year.

There are many SG-plasticity models in the technical literature, sometimes categorized as lower-order or higher-order models.

The problem is :

the constitutive models include the gradient of plastic parameters (e.g. plastic slip).

There is an immediate opening for a Ph.D. student in the Department of Materials Science and Engineering at Missouri University of Science and Technology (Missouri S&T - formerly University of Missouri-Rolla). The Metallurgical Engineering program at Missouri S&T is one of the largest and most respected in the U.S. (http://mse.mst.edu).

The Ph.D. research project is about developing a coupled phase-field crystal plasticity model for predicting stress-strain-microstructures relations during deformation.
