ageing viscoelastic
Hello everone
I am recently interested in viscoelastic composite materials with ageing effect. I will be very pleased if someone can advise me how to find a constitutive law with ageing effect.

IMECE 2015: Student Travel Awards and Best Paper Contest
Dear IMECE Attendees:
The Applied Mechanics Executive Committee (AMD-EC) is pleased to announce the 2015 IMECE student travel award and best paper competition.
PhD Positions – Computational Mechanics
PhD Positions in the area of computational mechanics are available at the computational biomechanical laboratory in the School of Mechanical and Aerospace Engineering at Oklahoma State University.
The candidates are required to have a MSc. degree in Mechanical Engineering or in a closely related field.
Only Candidates with strong background in numerical simulations, finite element analysis, and computational solid mechanics are encouraged to apply.
Excellent programming skills and experience with high performance computing are strongly desirable
On the modeling of asymmetric yield functions
In the context of metal plasticity, the yield function of a metal polycrystal is its most complex macro-characteristic. Letting aside the questions of kinematic or distortional hardening, the basic problem is geometric in nature: to design a family of convex surfaces capable of reproducing a wide range of experimental, or theoretically predicted data. While many satisfactory solutions have been proposed for the modeling of symmetric (with respect to the origin of the stress space) yield functions, the more general case of asymmetric functions has not witnessed comparable progress.

Is energy conservation satisfied in the current deformation application schemes in molecular dynamic simulations?
In our recent paper, we examined the energy conservation for the current schemes of applying active deformation in molecular dynamics (MD) simulations. Specifically, two methods are examined. One is scaling the dimension of the simulation box and the atom positions via an affine transformation, suitable for the periodic system. The other is moving the rigid walls that interact with the atoms in the system, suitable for the non-periodic system.
analysis Composite at Abaqus
Hi every one
I try to analysis my Model at Abaqus. I want to use continume shell model to create the composite layer. The model shape is so complex and I can not use Hex meshing. Abaqus just meshing the model as Tetra element. And my problem is abaqus do not accept tetra az composite layer at element type. I try to daturm the model very smal part until may be can define hex element but its not work. There is any way I can use tetra meshing for continume shell.
