Help compile list of available micromechanics codes

Computer simulations will be used more and more for composites design and manufacturing. Before an engineer can simulate, there are at least two questions: what are the tools available and which one works for my problem. Thus, as a start, cdmHUB plan to compile a list of micromechanics codes for the community, including commercial codes, public domain codes, or research codes. To make the list as complete as possible, we need your help.

Transverse shear stresses in Reissner Mindlin theory

How is it possible to obtain the transverse shear stresses correctly, not constant, by Reissner Mindlin theory?

Equilibrium equation would be the first solution, but, once the second derivatives of bilinear shape functions are zero, no results is appeared.

 

Thanks in advance for any help!

Two Post Doctoral Positions in Advanced Synthesis and Characterization at Rice University

Position Description: Two postdoctoral associate positions in the area of advanced synthesis and nano/micro-scale characterization of nanoparticles are available at Rice University. Various techniques will be applied to synthesize and self-assemble size- and shape-controlled silicate nanoparticles followed by nano- and micro-characterizations including a myriad of probes such as electron microscopies (TEM, XRD, SEM, AFM), ICP, XPS, NMR, porosimetry, dynamic mechanical analysis, nanoindentation, etc.

Virtual Special Issue: 'Outstanding research contributions in the area of nonlinear continuum and computational mechanics'

The 2014 Nathan M. Newmark Medal was awarded to Professor Herbert A. Mang at the annual ASCE Structures Conference, which took place in Boston, April 3–5, 2014. Professor Mang was awarded the Newmark Medal for his outstanding research contributions in the area of nonlinear continuum and computational mechanics that clarified the cause of collapse of important concrete structures and quantified the influence of the initial post buckling behavior of metallic structures.

modeling analysis of microstructure phase transformation in an alloy

Hi every one,

I need to modeling a thermal analysis of a microstructure of steel or other alloy by FEM or XFEM. so i need some metallurgical data for phase transformation.for example at which temperature or time martensit converts to austenit or etc. I also need how I can model this microstructure in abaqus that has change in boundries due to phase transformation. i appreciate if someone help me.

thanks

Coupling GSM/ALE with ES-FEM-T3 for fluid-deformable structure interactions

In light of the effectiveness of the edge-based smoothed finite element method (ES-FEM-T3) and arbitrary Lagrangian-Eulerian gradient smoothing method (GSM/ALE) in, respectively, solving the pure solid and fluid flow problems using three-node triangular elements, they are coupled together in the present study to solve the more challenging fluid-deformable structure interaction (FSI) problems based on the weak coupling algorithm.

Modelling of Dislocation-Microstructure Interaction at a Short Crack Tip

This project aims to model dislocation-microstructure interaction at a crack tip and associated short crack growth for nickel alloys.

critical stress for delamination in multilayers

could someone tell me some equation to get the critical stress for delamination in multilayers?

Thanks,

 

Question on Fatigue crack growth C and m Paris Law

Are m and C in the paris law equation dependant on the material property or geometry?

For example if using the same material with different thickness, do the C and m values change? For clarity assume centre notched plates, with different plate thicknesses but same material (steel or aluminium).

 

I appreciate your time.

 

 

Ultra-Strong Collagen-Mimic Carbon Nanotube Bundles

 In spite of worldwide research, carbon nanotubes (CNTs) still have not fully realized their

 original promise as ideal reinforcements for composite materials due to a number of

 challenging issues such as weak interface, poor dispersion, misalignment and lack of optimized

 design. Here we propose a bio-inspired structure of CNT bundles with controllable

 crosslink density and staggered pattern of organization that mimic the architecture of

 natural collagen fiber. Molecular mechanics (MM) simulations show that, under tensile
