High strain rate loading

A unified mechanics theory-based model for temperature and strain rate dependent proportionality limit stress of mild steel

Submitted by Cemal Basaran on

Strain rate and temperature dependent elastic limit of mild steel is investigated by developing a dislocation incipient motion-based proportionality limit stress model. Temperature effect on strain energy of an edge dislocation is modeled by using unified mechanics theory. Unified mechanics theory-based index, called thermodynamic state index, is used to model thermally assisted degradation of strain energy. Kinetic energy due to thermal vibrations is added to the kinetic energy of an accelerating dislocation.

I am looking for a post-doctoral research fellow with a high academic profile to join me on the PhotDyn project. The topic concerns the development of novel high strain rate testing procedures based on ultra-high speed deformation imaging and inverse identification. I am mainly looking for someone with expertise in constitutive modelling of materials. The detailed job description can be consulted here.
