Hard-magnetic soft materials (HMSMs) consisting of an elastomer matrix filled with high remnant magnetic particles can exhibit flexible programmability and rapid shape changing under non-contact activation, showing promising potential applications in soft robotics, biomedical devices and flexible electronics. Precise predictions of large deformations of hard-magnetic soft materials would be a key for relevant applications.

Intro

The research is concerned with modeling of electroactive soft materials. Preference will be given to candidates with background in nonlinear finite element methods and constitutive modeling.

If you are interested, please send an email to me at: cvjmah@technion.ac.il with a single PDF file containing your CV, grades, names of two references, and a brief description of how your experience and background meet the requirements for this position.

Dear iMechanicians,

Let me bring your attention what I believe is the most comprehensive study in the area of hydrogen embrittlement of additively manufactured materials. You can find all details here:

One the main challenges of developing data-driven models is the data-hungry nature of Artificial Neural Networks (ANNs). In our recent paper, we introduced a data augmentation approach to expand a small original dataset without conducting extra expensive high-fidelity simulations. We then used the original and augmented datasets for developing ANN models for non-linear path dependent composites. The obtained results showed the great impact of the data augmentation approach on the accuracy of the data-driven models.

I am happy to share our paper entitled "Mechanisms of failure of aluminium-based Whipple shields under hypervelocity impact: insights from continuum simulations" published recently in Springer Nature journal Acta Mechanica.

Our research group has two projects for Ph.D. students.

The microMechanics of Deformation Research Group (mMOD) in the Department of Materials Science and Engineering at Rutgers University is seeking a Post-Doctoral Associate to perform research under an internal award from the Rutgers TechAdvance program. The goal of the project is to extend a recently developed technique for constructing finite-element-based physics-informed neural network (FE-PINN) surrogate models to nonlinear problems in mechanics of materials (and beyond).

Do you want to understand how digitalization can revolutionize civil engineering structures? Do you want to bridge the gap between academia and industry in your daily work? Are you eager to share your research with our students so that they can make the difference tomorrow? Then you could be the new colleague we are looking for. The Department of Civil and Architectural Engineering of Aarhus University is looking for a visionary Assistant Professor (Tenure Track)/Associate Professor in the area of Digitalization for Structural Engineering.

We have 2 postdoc openings in the field of laser fusion additive manufacturing of metals at Tsinghua University. The candidates are required to have expertise in synchrotron x-ray techs, metal additive manufacturing, electron microscopy (TEM/SEM), grain growth, phase transformation, or micromechanics. This is a two-year appointment with the possibility of renewal. See more information here (in Chinese).

Petals and leaves are usually curled and exhibit intriguing morphology evolution upon growth, which contributes to their important biological functions. To understand the underlying morphoelastic mechanism and to determine the crucial factors that govern the growth-induced instability patterning in curved petals and leaves, we develop an active thin shell model that can describe variable curvatures and spontaneous growth, within the framework of general differential geometry based on curvilinear coordinates and hyperelastic deformation theory.

We recently established Multiscale Structural Mechanics on github along with the codes (

This paper is dedicated to Professor Nasr Ghoniem on the occasion of his retirement.

Abstract

A continuum mechanical model of coupled dislocation based plasticity and fracture at finite deformation is proposed. Motivating questions and target applications of the model are sketched.

We have two openings for PhD studies at University of Massachusetts, Lowell, Department of Mechanical and Industrial Engineering.
