Interlaminar Stresses

Submitted by nav_mech35 on
Dear Sir/Madam,
Interlaminar stresses in Composites
I have modelled Plain Stress problem in hypermesh(Input deck is created in Hypermesh to solve in Abaqus).Layup sequence is [0/90/90/0], am getting the Stresses( σ11, σ22, σ12) in top and bottom layers only, but unable to get the stresses at each Interface, If any one knows how to write the code, please reply back.

Tenure-Track Faculty Position in Materials Science at Villanova University

Submitted by Gang Feng on

The Department of Mechanical Engineering seeks an outstanding individual for a full-time tenure-track position in materials science with emphasis on the fabrication of micro and nanoscale materials and devices. Especially encouraged are applicants with interest in sustainable energy. The opening is at the Assistant Professor level but candidates with strong records will be considered for appointment at a higher level.

PhD/PostDoc position at University of Twente (NL): Hierarchical multi-scale modeling

Submitted by katia bertoldi on

The scientific goal of the project is to develop a multi-scale computational method that uses a single hierarchical data-structure as basis – involving also multiple fields. Starting from mesoscopic structures (particles or domains) a grid is constructed on a hierarchical, tree-based data structure. The hierarchical approach allows for micro-macro transition, coupling of different fields, and coarsening or refinement – where possible or needed, respectively.

I have a problem on shear failure for the material Ti-6Al-4v with ABAQUS

Submitted by Yancheng ZHANG on

hello, every one

recently,I need to develop model on the material of Ti-6Al-4v with Abaqus, I will use both Johnson-cook damage and shear damage for damage evolution,however, i am confused on the parameters for shear failure:

1)the parameter "ks", i can't find this value on internet;

2)the fracture energy for damage evolution in shear failure, the value should be the same with Johnson-cook,help example gives the same value, but i think it should be KII value for shear fracture,not KI.
