The principal stress rotation (PSR) occurs in many geotechnical engineering applications. The PSR can lead to additional plastic deformations in soil. However, the PSR impact is generally neglected in the study of geotechnical engineering. The project aims to comprehensively study impacts of the PSR on soil behavior from different perspectives. Experimental study will be conducted by using state-of-the-art experimental facilities including the Variable Direction Dynamic Cyclic Simple Shear system (GDS UK) and Hollow Cylinder Apparatus (GCTS USA). Elastoplastic constitutive models will be developed to simulate soil stress-strain responses. The discrete element method will be used to explore fundamental mechanism under the PSR. The PSR soil model will be implemented into software of the finite element method to study boundary value problems.
Requirements: The candidate should have a first class or upper second class honors degree, or a master’s degree (or equivalent qualification), in Civil/Mechanical/Geology engineering. Evidence of good spoken and written English is essential. The candidate should have an IELTS score of 6.5 or above, or an equivalent qualification, if the first language is not English. This position is open to all qualified candidates irrespective of nationality.
Degree: PhD degree will be awarded from the University of Nottingham upon successful completion of the program.
