A computational model for arbitrary brittle crack propagation, in a fault-like layer within a 3-d elastic domain, and its associated quasi-static and dynamic fields is developed and analyzed. It uses an FFT-based solver for the balance of linear momentum and a Godunov-type projection-evolution method for the crack evolution equation. As applications, we explore the questions of equilibria and irreversibility for crack propagation with and without surface energy, existence of strength and toughness criteria, crack propagation under quasi-static and dynamic conditions, including Modes I, II and III, as well as multiaxial compressive loadings.
Title: Modeling and Simulation Engineer Category: Full-time position in industry Employer: Schlumberger Technology Corporation Location: United States, Texas, Sugar Land Opening Date: 04/01/2021
Two PhD positions are available within the Department of Biomedical Engineering at the University of Texas at San Antonio for Summer or Fall 2021 in the area of injury biomechanics research focused on traumatic brain injury and computational modeling.
The overall goal of this research, headed by Dr. Marzieh Memar, is to integrate computational and experimental techniques to unfold mechanisms underlying traumatic brain injury (TBI).
Deadline to submit your abstract to USNCCM2021 is fast approacing (Februart 5). If you are working with machine learning, uncertainty quantification, optimization or a related topic, consider the following symposia:
USNCCM2021: MS309Data-driven Science with Uncertainty Quantification, Machine Learning, and Optimization
This mini-symposium has been quite popular and with high quality speakers in the last editions of USNCCMs and WCCMs. We hope it stays this way ;)
I'm current guest editor on a Special Issue of the MDPI Journal of Applied Sciences. This is a journal with an impact factor of 2.474.
The aim of this Special Issue is to explore the re-engineering of engineering through the integration of advanced digital technologies. Research papers or case studies involving any discipline of engineering are welcome. Topics may include, but are not limited to, the following:
We are writing to invite the mechanics community to participate in the upcoming U. S. Association for Computational Mechanics (USACM) virtual thematic workshop on “New Trends and Open Challenges in Computational Mechanics: from nano to macroscale”, to be held online on March 25th and 26th, 2021.
Please consider submitting an abstract to the Symposium Mechanics and Manufacturing of Architected Materials for the 2021 Virtual Mach Conference which will take place on April 7-9, 2021
The deadline for abstract submission is January 30.
this post is to inform you that, due to personal reasons, unfortunately, Prof. René de Borst will not be able to deliver his presentation this Friday. Accordingly, the webinar scheduled for Friday 29/01 has been cancelled.
We look forward to welcoming you all to the next TAFMech webinar:
Duration: 36 months
There is an available PhD position at the Institute of Physics, Czech Academy of Sciences in Prague to work under the modelling of the non-linear micro-/nanomechanical systems.
Spider silk is a protein material that exhibits extraordinary and nontrivial properties such as the ability to soften and decrease its length by up to ∼60% upon exposure to high humidity. This counter-intuitive process is commonly called supercontraction and is the result of a transition from a highly oriented glassy phase to a disoriented rubbery phase. In our new paper (published in biomacromolecules) we derive a model that explains the origins of the supercontraction phenomena.
We recently published a review article on "Elastic instabilities, microstructure transformations, and pattern formations in soft materials" in Current Opinion in Solid State and Materials Science.
If you are interested in the most recent advances in physics-based Fatigue, Fracture, Failure Prediction, and Structural Health Monitoring You may find this publication helpful.
Our group has several openings for fully-funded graduate students in computational and experimental mechanics of biological and engineered materials. Our primary goal is to link traumatic brain injury (TBI) with multiscale, multiphysics damage evolution in the brain using experimentally verifiable computations and simulations. We are also interested in designing advanced material for TBI protection.
A PhD student is being sought to fill an opening in the Gross Materials Lab (group website: andrewjgross.com) at the University of South Carolina. Research activities are focused on the design, fabrication, and characterization of architected materials. Students must be capable coders to be considered. Prior experience configuring optical equipment and National Instruments DAQ hardware is valuable, but not required. Students interested in or having prior experience with finite element modeling, mechanical property testing, and 3D printing are strongly encouraged to apply.
Applications are invited for two University Lectureships in Mechanics and Materials Engineering, to be known as the 'Granta Design University Lectureships in Engineering'.
