People associated with RMML work either with metallic materials or polymeric materials, based on which they are associated with one of the two sub teams of RMML as mentioned below:
Team Metallic @ RMML
Name
Rajwinder Singh
(PhD Student)
Association with RMML from:
August 2014
January 2015
January 2016
January 2017
December 2017
Type of association with RMML
Rajwinder Singh is working on his PhD that involves investigations into the short crack nucleation and propagation in metals under monotonic and cyclic loading through experimentation and simulation. He is also working on the effect of hydrogen embrittlement on the mechanical properties of metals especially short fatigue crack propagation.
Rakesh is working on his PhD dealing with computational modeling of the effect of micro-structure on fatigue crack initiation in metals under hydrogen environment. Rakesh uses a coupled framework of dislocation density based crystal plasticity model with slip-rate based hydrogen transport model to identify the hydrogen distribution in metallic microstructure that further paves the way for better modelling of the damaging effects of hydrogen on the material properties, the phenomenon termed as hydrogen embrittlement.
Navneet is working on development and evolution of cavitation-resistant composite coatings for hydro turbine steels.
Aman is working on Hydrogen Embrittlement of Nickel. Investigating Crack Nucleation sites on the basis of Schmid Factor and Elastic modulus.
Sandeep is mainly working on the fatigue behavior of additive manufactured product made of IN718 in as a function of surface roughness. He doing both experimental and simulation for the same. In simulation he is using MATLAB, ABAQUS, Fe-Safe.
