#fracture

The mechanical properties of alloys, and thus their susceptibility to damage and failure, are determined by their chemical composition as well as by their process-dependent microstructure. While microstructural modifications are well-known to improve, e.g., the yield stress or fatigue lifetime by orders of magnitudes, no thorough atomistic methods for systematic high-throughput exploration of the microstructure space have been performed yet. 

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 as part of an NSF CAREER award project aimed at understanding the fundamentals of fracture in metals. Research tasks will include the development of a machine learning framework for training surrogate models which couples with the finite element method and analyzing large atomistic simulation datasets.

There is 1 fully-funded Ph.D. studentship (3-year bursary) available for a 1st November 2023 start.

A description of the research programme is given in the enclosed pdf.

Preferred applicants should hold a degree in Engineering with a major in Solid and Structural Mechanics.

In our recent study published in ACS Applied Materials & Interfaces, using a multiscale modeling technique, we investigated how the combination of nanofibrillation and interfacial tuning can have a synergistic effect on the stiffness-toughness balance in rubber-toughened nanocomposites.

3rd International Symposium on the Fundamentals of Fracture

26.03. - 31.03.2023 in Dresden, Germany.

Fracture is a complex multi-scale, multi-physics phenomenon and a fundamental, mechanism-based understanding is needed to disentangle the underlying, interacting processes. With this topical session we aim at connecting specialists from the fields of solid-state physics, materials science, continuum mechanics, statistical physics and mathematics to cover theory, numerical modeling and experiments related to:

Hello fellow mechanicians,

I have immediate and upcoming openings for graduate students and post-docs who have interest and experience in solid mechanics. I am especially in need of someone with Abaqus/FEA experience.

Dear colleagues, 

We would like to cordially invite you to participate in the Mini-Symposium on "Quasibrittle Fracture of Heterogeneous Composites: Modeling and Characterization" at the ASCE Engineering Mechanics Institute (EMI) Conference to be held in Baltimore, Maryland from May 31 to June 3, 2022. 

In situ dendrite reinforced Bulk Metallic Glass matrix composites (BMGCs) are known to overcome poor ductility and fracture response exhibited by monolithic bulk metallic glasses (BMGs). In this paper (Shear fracture in bulk metallic glass composites) recently published by our group in Acta Materialia, we report mode I and mode II fracture experiments on the above in situ BMGCs containing transforming and non-transforming dendrites.

I would like to direct your attention to our 1st Virtual FRASCAL Colloquium which is organized by the DFG funded Research Training Group GRK 2423 "FRASCAL - Fracture across Scales".

Open PhD positions are available in the Materials and Mechanics Lab, in the Department of 

A Postdoctoral researcher position is available in the Anderson lab in the Department of Evolution, Ecology and Behavior at the University of Illinois, Urbana-Champaign. The Anderson lab seeks a post-doctoral scholar with strong experience in some combination of the following: experimental fracture mechanics, Impact dynamics, dynamic fracture modeling, energetics and/or biomechanics. Please see the attached ad for more information. More information about the Anderson Lab can be found here: https://www.philipslanderson.com/

Dear iMechanicians,

I hope this paper is of interest to you. We show that quasi-Newton methods make monolithic phase field fracture implementations very robust. Convergence and computations times orders of magnitude smaller than the usual staggered approaches are demonstrated in complex problems such as unstable cracking, fatigue or dynamic crack branching.

Dear colleagues,

I hope some of you may find this work interesting. We show, analytically and numerically, that strain gradient plasticity predicts the existence of an inner elastic field adjacent to the crack tip, reminiscent of a dislocation-free zone. The fact that elastic strains dominate plastic strains near the crack tip implies a paradigm-shift with respect to previous crack tip asymptotic studies in plasticity and gradient plasticity, which neglect elastic strains.
