The Advanced Computational Materials Engineering Laboratory (ACME Lab: https://acmelab.ua.edu) in the Department of Mechanical Engineering at The University of Alabama is seeking candidates for a fully-funded PhD position in the area of deformation mechanics to begin August 2022.

PhD position(s) is available for Spring 2022 in the Engineering Mechanics program in Aerospace Engineering Department at Iowa State University to perform theoretical and computational part of work on NSF-funded projects on the interaction between phase transformations and plasticity. Phase-field, micromechanical, and macroscale simulations using FEM are of interest, in close collaboration with high-pressure experiments performed in our lab. Please send vita to Prof. Valery Levitas ( vlevitas@iastate.edu )

A one-year post-doc position is available in our research group at the University of Houston with a start date of 1 September 2021. 

We are interested in understanding how microstructural aspects govern material failure. Our approach relies on formulating theoretical frameworks that are informed by experiments and implementing them computationally.

Join us to expand in more novel directions:

(i) Data-driven plasticity and failure;

(ii) Phase-field approaches to plasticity and failure;

The microelectronics revolution is one of the most influential drivers of current industrial developments. To probe the mechanical properties of ever shrinking materials and components, nanoindentation has come to be an omnipresent and indispensable method. In a recent combined experimental and computational approach, an international team of scientists was for the first time able to resolve the dynamic atomistic processes taking place at the elastic-plastic transition during nanoindentation.

Dear Colleagues,

We would like to cordially invite you to the Computational Geomechanics mini-symposium at the ASCE EMI 2020 Conference, which will take place on May 26–29, 2020 at Columbia University in NYC. The abstract submission is now open until January 15, 2020 (Link: https://submissions.emi2020.org).

Dear colleagues,  We would like to make you aware of a mini-symposium we are organizing for WCCM-ECOMAS in 2020, to be held in Paris on July 19-24, 2020. The symposium is entitled "Computational Geomechanics", and focuses on modeling aspects related to geological materials.

Tittle: Multiple localization and fragmentation of thin-walled metallic tubes subjected to dynamic axial penetration

Supervisor: José A. Rodríguez-Martínez

More often than not I find in the books I read the information about the von Mises yield cirterion without mentioning any contribution of Maksymilian Tytus Huber in this field. E. g. I'm reading now "Materials for Nuclear Plants" by Wolfgang Hoffelner. When discussing the yielding conditions of the material he refers to von Mises, Hencky and even to Maxwell, but does not mention Huber. M. T. Huber anticipated to some extent the criterion of Mises already in 1904 (von Mises published his paper in 1913), but is not recognized by most of mechanicians.

Hi everybody,

I am studying the plastic deformation of sheet metal. Recently, I study about stress update scheme in finite element analysis using return mapping method. For this problem, we can calculate the increment of stress components, Δσ for a given value of strain components Δε using elastic predictor - plastic correct scheme. Since Δε = Δεe +Δεp, first, we assume Δεp=0 and check the yield criterion. Then, we find Δεp to satisfy the yield criterion as well as the consistent condition.

However, I have a question as the follows
