AIMS AND SCOPE

Applications are sought for four Post-Doctoral Research Associates and two PhDs to join a very active research group at Cardiff University, UK (School of Engineering).  Based in Cardiff, there will be frequent interactions with the University of California, San Diego as well as major aerospace companies in the UK. The research will formulate and develop numerical methods for mulitiscale and multiphysics design optimisation using level set topology optimization.

One or more of research experience in the following areas are required.

The Department of Aerospace Engineering at the Indian Institute of Technology, Madras is seeking to fill Assistant Professor vacancies in the following research areas.

1) Experimental Structural Mechanics/ Composites
2) Aircraft Aerodynamics (experimentalists preferred)
3) Control and Flight Mechanics of Aerospace vehicles
4) Aircraft Design (aerodynamic/structural)

Since real specimens deform three-dimensionally, 2D modeling approaches cannot predict the flow curve of the material precisely. The predicted flow curves obtained from 2D modeling can, however, be correlated to the 3D ones by introducing a correlation factor, We quantified by the stress ratio (σ_3D/σ_2D) based on the 2D and 3D RVE calculations for DP600 steels with various martensite phase fractions (V_m=0–50%) at different equivalent plastic strains varying from ε^p_eq=0 to 0.1.

Recent literature suggests that nano-twinned materials posses both high strength and ductility. Such unusual properties have been attributed to the unique ability of coherent twin boundaries in affecting dislocation slip transfer mechanisms unlike other types of grain boundaries of lesser symmetry. A combination of experimental and theoretical studies is presented to rationalize the macroscale attributes of nano-twinned NiCo alloys of four different compositions (please see the attached pdf below for the paper). 

A new perspective on model reduction for nonlinear multi-scale analysis of heterogeneous materials. In this work, we seek meaningful low-dimensional structures hidden in high-dimensional multi-scale data.

Recently, unusually high detachment rates of a myosin from actin were reported with a force spectroscopy technique. Here, we show that these high rates may be due to the coupling between bond breaking and state transition. Based on a kinetic model for single myosin, rates of bond breaking between myosin and actin at different nucleotide states are systematically extracted for the first time. Our results clearly indicate that myosins may adopt much higher transition rates than bond breaking rates at different nucleotide states at relatively low forces.
