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). The mini-symposium description is given below:
Hello everyone,
I have created a UMAT code for J2 elasto-plasticity with isotropic hardening for 3D solid elements.
At this point I would like to support also plane stress shell elements. What changes in the code are
suggested? The already implemented code, takes as input the strain tensor at time tn and the strain
increment tensor and updates the stress at time tn+1 and calculates the material Jacobian and
achieve quadratic convergence. The stress and strain tensors are manipulated as 6x1 vectors and the
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 participate in a pair of collaborative projects with a Department of Energy National Laboratory. The projects are focused on using discrete dislocation dynamics (DDD) simulations to understand dislocation patterning in deformed metals, and molecular dynamics (MD) simulations to understanding crack initiation in hydrogen-affected steels.

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

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
