Shear Unfreezing Explains Yielding, Plasticity and Neck Initiation of Glassy Polymers
Peihan Lyu, Zhaoyu Ding, Masao Doi +1
Yielding, plasticity, and necking are central to the mechanical performance of materials, yet a concise unified physical picture of how these nonlinear responses arise remains lack…

Polymeric Solvents Control Swelling-Induced Surface Creasing
Zechao Jiang, Zhaoyu Ding, Shaohua Yang +7
Surface creasing in swelling polymer gels is commonly attributed to compressive strain or interlayer mismatch, yet its general control remains unclear. Here we show that solvent po…

A Unified Model for Non-Fickian Diffusion and Anomalous Swelling of Glassy Polymer Gels
Peihan Lyu, Zhaoyu Ding, Masao Doi +1
A sheet of glassy polymers placed in a solvent shows swelling behaviors quite different from that of soft polymers (rubbers and gels). (1) Non-Fickian diffusion (called case II dif…
