Introduction
I am working on fracture mechanics focusing on the role of irregularities and the strain rate on brittle and ductile fracture. The research includes numerical modeling and the finite element analysis with some experiments and damage model calibration.

Article
Dynamic fracture tests are carried out for four groups of hole-containing edge impacted PMMA specimens. The crack growth velocity, crack path, and dynamic toughness are extracted from the experiments using high-speed photography and digital image correlation. The importance of the interaction between the in-coming stress wave and the pre-existing h...

Article
Full-text available
Monte Carlo simulations and probabilistic modeling are employed to understand the strength distribution of a planar bundle of local load-sharing fibers. The fibers are distributed randomly within a unit square according to a Poisson process, and the fiber strengths are Weibull distributed with exponent ρ. Monte Carlo failure simulations of bundles...

Project
Gyroid structures are commonly found in nature due to the high strength to weight ratio and the isotropic properties. The lattice structure is numerically analysed to develop the yield surface.
Project
The research examines the influence of the operating parameters on the formability of ASTM A992 steel using GTN model embedded in finite element analysis to improve the formability of the material under environments. Effect of the strain rate, temperature, shear load and friction are considered as the operating variables to analyse the evolution of the FLC.
Project
Behavior of soft interface under different strain rates are studied on 3D printed specimens. This is a collaboration with Dr. Stephan Rudykh and Dr. Slava from Technion-IIT. A reverse tapered triangular specimen is designed with a soft interface using 3D printer. The specimens are tested under quasi-static and dynamic loading to evaluate the influence of the strain rate on the fracture. Interfaces at several angles are introduced to examine the fracture characteristics. Numerical analysis with finite element method is to confirms the generalities.
