In this paper we formulate a geometric nonlinear theory of the mechanics of accreting-ablating bodies. This is a generalization of the theory of accretion mechanics of Sozio and Yavari (2019). More specifically, we are interested in large deformation analysis of bodies that undergo a continuous and simultaneous accretion and ablation on their boundaries while under external loads.

The Materials Theory Group at the School of Materials Engineering of Purdue University has a post-doctoral opening in the area of Mesoscale Plasticity of Irradiated Crystalline Solids.

The postdoc will use discrete and continuum dislocation dynamics to investigate the deformation and fracture of structural alloys for fusion applications. A background in continuum mechanics and crystal plasticity is required for this position. The ideal candidate is one who is strongly interested in the fundamental aspects of deformation and fracture of materials and related computational modeling, and must have excellent programming skills in Fortran and/or C++. The Postdoc will interact with our group members and with our collaborators outside Purdue: Professors Grethe Winther and Henning Poulsen at the Technical University of Denmark who are performing synchrotron measurement of dislocation structures in deformed metals (see related research at https://pmp.dtu.dk/).

For inquiry about this position, please send an email to Professor Anter El-Azab (aelazab@purdue.edu). Interested candidates can send a curriculum vita with list of publications, half a page statement of research interests, and the names of two or three references to the email above.

The Materials Theory Group performs theoretical and computational research in the areas of mesoscale plasticity and dislocation dynamics, radiation effects in materials, microstructure evolution, phase field method development, phonon and electron thermal transport in crystalline solids, and computational methods for materials science and mechanics.

All qualified individuals, including diversity candidates are encouraged to apply.

We have 1 PhD position funded by NSF in 2024 Spring at SUNY Binghamton, New York. 

The research will be on multiphysics modeling & simulation for soft functional composites in flexible electronics. The major task will be performing multiphysics/multiscale finite element simulation (ABAQUS), nonlinear constitutive modeling, micromechanics modeling, etc.  For more info about the lab, please refer to http://puzhang.weebly.com/ .

We are looking for a postdoctoral researcher to work on the project MECA-ICTUS, a 3-year project funded under the Generación de Conocimiento 2022 call of Agencia Estatal de Investigación.

1. Introduction

One fully supported Ph.D. position is open immediately in Advanced Hierarchical Materials by Design Lab at the University of Alabama on multiscale modeling of materials and processes. The goal of this research project is to use machine learning algorithms to design materials and their synthesis process. 

Diverse science and engineering problems are governed by delay differential equations (DDE). Seeking periodic solutions of DDEs is crucial for many nonlinear dynamic systems. The incremental harmonic balance (IHB) method is an efficient semi-analytical ap- proach for periodic solutions of DDE.

The Design & Uncertainty Quantification group at The University of Iowa, led by Professor Sharif Rahman, is looking for two new Ph.D. students, who are capable of and interested in performing high-quality research on solid mechanics, uncertainty quantification, and design optimization. The research, supported by U.S. National Science Foundation, requires building a solid mathematical foundation, devising efficient numerical algorithms, and developing practical computational tools, all associated with stochastic analysis and design of complex materials and structures.

The thermal-hydraulics as well as flow-induced vibration of wire-wrapped rod bundles calls for accurate and efficient liquid metal flow simulation and prediction, yet it remains a challenge due to the complex geometries and high Reynolds number flow in wire-wrapped rod channel. Previous efforts towards this goal exclusively adopts full-order modeling (FOM), which is prohibitively computation-intensive.

Cracks usually propagate dynamically that makes them so dangerous. However, most crack simulations are based on quasi-static analyses because they are simpler than the dynamic ones. Is it correct to use quasi-static analyses instead of the dynamic ones? Will the quasi-static and dynamic simulations provide similar results? We try to answer these questions in the present work. We compare results of quasi-static and dynamic simulations of crack propagation in aneurysm material.

The mechanism of drag reduction via polymer additives is long debated in the literature. We present results of 3D numerical simulations of the realistic pipe flow where material instabilities develop into turbulence. We observe in the simulations that the addition of the polymer solute suppresses the chaotic turbulent motion, indeed, in accordance with the experimental observations of the phenomenon.

 The  Multi-Scale Mechanics and Materials by Design Lab at Purdue University is seeking a highly motivated and talented individual to fill a postdoctoral research position in the field of biomimetic fiber-reinforced composites. This position offers a unique opportunity to work closely with Professor Zavattieri and collaborate with leading companies in the composites industry, focusing on a novel application of these materials.

We present a general formalism for the analysis of mechanical lattices with microstructure using the concept of effective dynamic mass. We first revisit a classical case of microstructure being modeled by a  spring-interconnected mass-in-mass cell. The frequency-dependent effective dynamic mass of the cell is the sum of a static mass and of an added mass, in analogy to that of a swimmer in a fluid. The effective dynamic mass is derived using three different methods: momentum equivalence, dynamic condensation, and action equivalence.

1 Ph.D. position (36 months) within the research activity related to the PI ERC Consolidator Grant "SFOAM" will be funded by and available at the University of Trento (Italy). 

Multiple postdoc and one PhD positions are open at Tsinghua University. The research will take place at Tsinghua University’s Shenzhen International Graduate School (SIGS), located in Shenzhen, China, and is partly sponsored by NSFC and Tsinghua SIGS’s scientific research startup funds.

Multiscale.Sim 2022R2 version is now available globally.

Multiscale.Sim is an add-in tool for the Ansys Workbench environment (it's also compatible with Ansys Mechanical APDL). It can help to predict materials behavior using virtual material testing without having to rely on costly and time-consuming physical testing all the time. The software includes a templates library to easily create microstructure of materials. It's available in English and Japanese UI.

The Multiscale Modeling of Materials and Machine Learning Laboratory (M4L Lab: https://www.m4l-lab.com/) at Villanova University is looking for two Ph.D. students.
