Uncertainty-guided active learning for surrogate prediction of stream-finishing wear fields
Anand Kumar, Puli Saikiran, Vineet Dawara +1
In stream finishing, the wear experienced by a workpiece depends strongly on its orientation within the rotating abrasive media. Determining suitable orientations to achieve unifor…
Dynamic fragmentation of residually stressed solids: From microscopic instabilities to universal scaling
Vineet Dawara, Koushik Viswanathan
The dynamic fragmentation of residually stressed solids involves a complex interplay between stored elastic energy, stress wave propagation, and crack instabilities. In this work,…
On the onset of slip at adhesive elastic interfaces
Vineet Dawara, Koushik Viswanathan
The transition from static to dynamic friction when an elastic body is slid over another is now known to result from the motion of interface rupture fronts. These fronts may be eit…
Synthetic space bricks from lunar and martian regolith via sintering
Nitin Gupta, Vineet Dawara, Aloke Kumar +1
The prospect of establishing extra-terrestrial habitats using in situ resource utilization (ISRU) constitutes a long-term goal of multiple space agencies around the world. In this…
Design of a low-velocity impact framework for evaluating space-grade materials
Vineet Dawara, Ashok Bajantri, Harish Singh Dhami +2
Material deformation and failure under impact loading is a subject of active investigation in space science and often requires very specialized equipment for testing. In this work,…
Porosity governs failure in bioconsolidated space bricks
Vineet Dawara, Nitin Gupta, Arjun Dey +2
Understanding the mechanical response and failure of consolidated extra-terrestrial soils requires analyses of the interactions between propagating cracks the material's inherent p…
