CSS Talk by David Richard
David Richard presented a talk entitled “Bridging necking and shear-banding mediated tensile failure in glasses” that closed the 2nd Capriccio Special Seminar. He started with experimental observations that metallic glasses exhibit a failure mode transition from necking to shear-banding with decreasing temperature or increasing strain rate in tensile loading, which can be parameterized by the […]David Richard presented a talk entitled “Bridging necking and shear-banding mediated tensile failure in glasses” that closed the 2nd Capriccio Special Seminar.

New Paper in Mechanics of Materials
We are delighted to announce the publication of “Modeling steady state rate-and temperature-dependent strain hardening behavior of glassy polymers” in Mechanics of Materials. https://doi.org/10.1016/j.mechmat.2024.105044 This paper discusses the physical origin of rate- and temperature-dependent strain softening and strain hardening behavior in glassy thermoplastics based on molecular dynamics simulations and proposes a thermodynamically consistent constitutive model […]We are delighted to announce the publication of “Modeling steady state rate-and temperature-dependent strain hardening behavior of glassy polymers” in Mechanics of Materials. https://doi.org/10.1016/j.mechmat.2024.105044 This paper discusses the physical origin of rate- and temperature-dependent strain softening and strain hardening behavior in glassy thermoplastics based on molecular dynamics simulations and proposes a thermodynamically consistent constitutive model […]

New Paper in European Journal of Mechanics/A Solids
In this latest paper, we evaluate the impact of the molar mass distribution on the mechanical behavior of polymer nanocomposites. To this end, we employ coarse-grained molecular dynamics with a Kremer–Grest bead–spring model on samples with varying average molar mass and dispersity. We observe the expected increase in the mechanical performance for a larger average […]
