cohesive zone model
Research Fellow position in Computational Mechanics, Department of Mechanical Engineering, University of Southampton, UK.
Job Purpose: To make a leading research contribution to an industry-sponsored project on state-of-the-art finite element techniques to simulate needle penetration into skin working with the PI, A/Prof. Georges Limbert. You will join the national Centre for Advanced Tribology at Southampton (nCATS). In addition, you will work closely with the sponsor and contribute to the planning, writing and submission of reports and research publications.
Full Time Fixed Term for 18 months
Research Associate position in Computational Mechanics, Department of Mechanical Engineering, University of Southampton, UK.
Start date: between 1 November 2021 and 1 December 2021
Duration: 18 months (first phase of the project)
HOW TO APPLY?
Non-local plasticity effects on notch fracture mechanics (code included)
I hope some of you find this work interesting, the code with the control algorithm (Segurado and Llorca, 2004) to avoid convergence problems in cohesive zone model analyses of crack propagation can be downloaded from empaneda.com/codes (documentation and Abaqus input files are provided).

Are there any papers/documents on one dimensional bar problem with a cohesive zone element formulation? It should be a zero length non-linear spring in this case right? I am more interested in setting up the problem from the virtual work principles rather than a discussion of the results.
Thanks
A cohesive zone framework for environmentally assisted fatigue (code included)
I hope some of you find this work interesting, the code with the cohesive zone model for fatigue can be downloaded as a user element (UEL) subroutine for Abaqus from empaneda.com/codes

Postdoc position – Modeling dynamic fracture and fragmentation
A Postdoctoral fellowship is available at The Johns Hopkins University, Baltimore, U.S.A. in the area of fracture and fragmentation under dynamic loading conditions. The potential candidate should have a Ph.D. in an engineering discipline, a strong background in fracture mechanics and extensive computational modeling experience working with the finite element methods or some other numerical method with application to solid mechanics.
What are the regular iteration steps of cohesive model based FEM for crack problems
Hi,
I'm now start to learn cohesive zone model based FEM for crack problems. According the a regular coehsize model (bilinear for example), the relative displacement and the cohesive stress are both unknwon, so iteration is required. My question is that what are the regular iteration steps?
Thanks.
Fixation and Mechanical Properties of Implanted Cartilage Replacements - An overview of three recently published papers
Partial- and
full-thickness cartilage lesions of the knee caused by trauma, disease or joint
instability are a common disorder affecting people of all ages. Implanted
cartilage replacements (ICR) have the potential to overcome the limitations of
conventional treatment methods and are a promising approach to restore
functionality of the joint. In spite of some success in engineering
cartilaginous tissue, inferior biomechanical and biochemical properties of ICR
compared to native articular cartilage (AC) and inadequate quality of fixation
