PBPU Elastomer Network Architecture Determination via Corresponding States Analysis of Mechanical Behavior
Sushanta Das, Hari Ramakrishna Sudhakar, Hemant Nanavati
In this work we examine the effect of R=[NCO]/[OH] in the R=<1 regime, on the resultant structural topology of polybutadiene polyurethane (PBPU) elastomer networks based on hydroxy…

Defining Ideal Phantom Polymer Networks
Hemant Nanavati, Sushanta Das
Elastomers are modeled as networks with -functional junctions containing ideal, -segment, freely jointed chains (FJCs) per unit volume (p.u.v.). Our compact model of the…

Physical phenomena during nanoindentation deformation of amorphous glassy polymers
Prakash Sarkar, Prita Pant, Hemant Nanavati
We identify for visco-elasto-plastic (VEP) glassy polymers, physical phenomena during Berkovich nanoindentation, a locally imposed deformation. Live visuals via in situ nanoindenta…
