Arnav Rana’s work to appear in Engineering Fracture Mechanics

Arnav has made a nice contribution to the literature on J-Q theory, quantifying the limits of applicability of the theory in ductile fracture students, especially when crack planes are misaligned with respect to the material coordinate system. This highlights the importance of the consideration of plastic anisotropy when performing... More

Our article on the use of scaling analysis as a tool for the validation of CFD results appears in the journal of Thermal Science and Engineering Progress

In this article, we proposed scaling analysis as a simple approach to replace experimental measurements to validate CFD results. In fact, we used scaling analysis to validate the simulation results due to insufficient experimental results. The journal bearing housing of a gas turbine engine was studied in this work. The authors considered the... More

Our article on the MD simulations of spallation in polymers appears in the Journal of Applied Mechanics

In this article, we computed the spall strength of polyurethane samples by following two methods: (1) The indirect method (from the free surface velocity history, which is commonly used in experiments) (2) A direct method (from the atomic stresses in the spall region, which is possible only in MD) The results reveal that the...

Our work on the ballistic performance of SiC/polyurea nanostructures is published in Extreme Mechanics Letters

In this work, we conducted MD simulations to demonstrate that the ballistic limit velocity and the specific penetration energy of SiC/polyurea multilayers are significantly higher than the experimentally measured values of other protective materials. Moreover, we demonstrated that the specific penetration energy of a nanoscale target with a given... More
