ABSTRACT
Hi,
Is it possible to use micromechanical homogenization to simulate damage localization? The analytical procedures that I have come across, mostly gives a homogenized behavior of the composite and is suitable as long as the damage is diffused. Is there a way to obtain the behavior when the defects (for example microcracks) localize into a damage zone? Some lead or suggestions of reference materials would be of great help.
Thanks.
Our group has one postdoctoral position opening supported by Singapore University of Technology and Design (SUTD)-Digital Manufacturing and Design (DManD) Centre for the projects of design and fabrication of fiber reinforced composites, and nano/micro fabrication.
We are seeking self-motivated postdoctoral researchers with a strong background on solid mechanics and FEA simulation, and experience in composite fabrication, material preparation and characterization.
The successful candidate is required to have:
I am an undergraduate student conducting a research project involving the design of a tool to aid astronauts to perform experiments on lunar surfaces and would like to request some direction about which analytical tools would be best suited for this application (i.e. FEA or DEM software/techniques). The specific scenario of interest is to design a tool that can act as an anchor in a sand-like medium (regolith) on the surface of the moon.
Hi
I want to write a finite element code capable of modeling the pos-buckling behavior of plates. I have already written a FEM code for eigenvalue buckling analysis of plates.
I don't have any idea how to start.
I would be very grateful if someone could help me
thanks
To detail out,
My understanding of multiplicative decomposition of deformation gradient F =FeFp (see the attached figure) is
Fp indicates the shape change without inducing any stress
Fe leads to elastic stretching and rotation
If we consider dislocation effect( GNDs) that they have proportional relation with strain gradient, does it effect on way of homogenization or not? i mean at this situation can we use any methods of homogenization ? I'm looking into size effects at micro scale on macroscopic properties.i want to be sure if self consistent method is usable to as a method or not?

<p>A post-doctoral position in the general area of continuum simulations of high-strain rate impact phenomena is available in the Mechanical Engineering Department at Northeastern University. The specific goal of the project is to investigate the mechanics of cohesion following high velocity impacts. Knowledge of finite element theory, contact mechanics, plasticity and cohesive zone using customized codes and Abaqus are required. Experience with writing own finite element codes, Abaqus user subroutines and Python code will be helpful for the position.
The Department of Electrical Engineering at Stanford University (http://ee.stanford.edu/) invites applications for a tenure-track faculty appointment at the junior level (Assistant or untenured Associate Professor) in the broadly defined field of electrical and computer engineering. The department is especially interested in candidates in robotics and autonomous systems, hardware systems, and embedded systems. Priority, however, will be given to the overall originality and promise of the candidate’s work over any specific area of specialization.
