Energetics of Nucleation in Finitely Deformed, Phase-Transforming Soft Solids
Mrityunjay Kothari
Classical nucleation theory describes the rate at which stable nuclei form within a metastable parent phase by crossing a free-energy barrier set by competing bulk and interfacial…
The effect of interactions on elastic cavitation
Ali Saeedi, S Chockalingam, Mrityunjay Kothari
Cavitation refers to the sudden, unstable expansion of a defect or cavity within a material in response to applied loads, when the loads reach a critical threshold. It is widely re…
A thermo-mechanically coupled finite deformation model for freezing-induced damage in soft materials
Ali Saeedi, Ram Devireddy, Mrityunjay Kothari
In the U.S., approximately 17 patients die each day awaiting an organ transplant, a crisis driven by the inability to store organs long-term via methods like cryopreservation. A pr…
Push and Pull: Elastic Interaction Between Pressurized Spherical Cavities in Nonlinear Elastic Media
Ali Saeedi, Mrityunjay Kothari
Elastic interaction of pressurized spherical cavities embedded in a three-dimensional hyperelastic medium is computationally analyzed. Using finite element analysis across several…
Elastic Interaction of Pressurized Cavities in Hyperelastic Media: Attraction and Repulsion
Ali Saeedi, Mrityunjay Kothari
This study computationally investigates the elastic interaction of two pressurized cylindrical cavities in a 2D hyperelastic medium. Unlike linear elasticity, where interactions ar…
