The Center for Material Forming (Cemef) at Mines Paris (PSL University) is looking for a candidate for a PhD position on the computational modeling of sheet metal forming.
The project focuses on remeshing strategies for localized strain phenomena in automobile applications.
The industrial partner is for the moment undisclosed.

Applications are sought for a research assistantship in the field of wave propagation modeling. The position is supported by a monthly stipend and tuition and fees towards a PhD degree for up to four years (subject to satisfactory progress). The start date is flexible (January 2021 preferred). The student will be based in the Department of Engineering Science and Mechanics (www.esm.psu.edu) at Penn State University in Pennsylvania, USA (www.psu.edu).
Published in Physcal Review Letters: https://doi.org/10.1103/PhysRevLett.122.045502. Many materials are anisotropic. However, there is no widely accepted measure for characterizing the degree of elastic anisotropy. Here, assuming that the limiting case of extreme anisotropy should possess a positive semidefinite stiffness matrix, we propose three criteria to evaluate measures of anisotropy and show that the existing measures in the literature do not satisfy all of the proposed criteria.
Helices are ubiquitous building blocks in natural and engineered systems. Previous studies showed that helical ribbon morphology can result from anisotropic driving forces and geometric misorientation between the principal axes of the driving forces and the geometric axes. However, helical ribbon shapes induced by elastic modulus anisotropy have not been systematically examined even though most natural and engineered structures are made of composite materials with anisotropic mechanical properties.
Hi all,
I am doing microstructure analysis in 3D. To implement anisotropy, i need to give the orientation data. Does anyone know, how to give the orientation in ABAQUS?
The data i have in hand is Euler Angles... Can i give the data manually for four of five grains?
Also, please tell me about the ORIENT subroutine in ABAQUS...

Abstract:
The expansion behavior of cellular materials is especially attractive for potential applications such as design and development of bio-inspired adaptive materials since most of biological materials have a cellular microstructure at least at one of their hierarchical levels. Wood, bone, bamboo, ice plant and honeybee combs are examples of such natural materials.
Hi everyone,
According to a book chapter written by NL Hancox, 'Laminar construction of composites which is required if the reinforcing fibres are to be used efficiently and anisotropy reduced, can be a reason why composite laminates are vulnerable to impact damage.'
Now I have three questions;
1-What is meant here by the specified 'laminar construction to reduce anisotropy'?Does it mean to use different orientation for fibres in each ply to have an isotropic material at the laminate level?
Hi all,
I am currently working on micro-sphere model like the one used by Miehe, Ihlemann and Pawleski. I wonder if someone know a FEM code who use this type of model.
Thanks a lot
Joachim Guilie
