Highlights

1. Well-posedness of a general nonlinear state based peridynamic models.

2. A priori numerical convergence rate for finite difference approximations of state based peridynamic models.

3. Numerical verification of convergence rate for samples with growing cracks.

Two postdoc positions in computational modeling of metallic additive manufacturing are available immediately in the research groups of Prof. Jinhui Yan at University of Illinois at Urbana-Champaign (UIUC) and Prof. Wentao Yan at National University of Singapore (NUS). Successful candidates need to be self-motivated and have a solid background in mathematics, mechanics, numerical analysis, and programming (Fortran, C/C++, and Python).

Being able to create accurate medical devices that are closely matched to a patient’s unique anatomy requires precision imaging, measurements, and design. A critical part of PrinterPrezz’s unique medifacturing™ workflow is our process of turning magnetic resonance imaging (MRI) and computed tomography (CT) scans into a 3D CAD image that can be manipulated and used for 3D printing.

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.

This position is strictly for experienced candidates and is located at our Global R&T Centre in Kennesaw GA. Please get in touch with me if this role matches your experience. Job Description 

Following the success of three former meetings (Tokyo 2011, Tokyo 2013, Brno 2016), the fourth ISAM⁴ meeting will be held at FAU Erlangen-Nürnberg, Germany from August 5th to 8th 2019. 

This symposium is intended as an international forum for the presentation and discussion of the latest scientific developments regarding the atomistic and multiscale modeling of materials. We aim at bringing together specialists from multiple disciplines to network, exchange and generate new ideas related (but not limited) to

The Department of Mechanical and Aerospace Engineering in the School of Engineering and Applied Science at the University of Virginia seeks candidates for one Research Associate position to assist in experimental mechanics of advanced materials in Professor Xiaodong (Chris) Li's lab.

The Research Associate is expected to perform materials and mechanical characterization and finite element analysis of composite materials and coatings, and write reports and technical papers.
