strain localization

The 2023 edition of the advanced course on Modeling of Localized Inelastic Deformation, given by Milan Jirásek, takes place from 4 to 8 September at the Faculty of Civil Engineering, Czech Technical University in Prague.

Two advanced courses are offered at the Faculty of Civil Engineering, Czech Technical University in Prague in the first half of September 2022: Modeling of Localized Inelastic Deformation (LID 2022), delivered by Milan Jirásek from 5 to 9 September, and the

This study investigates the influence of physical aging on the deformation behaviors of poly(ethylene terephthalate)-glycol. The polymers are subjected to a quenched and an annealed heat treatment, followed by deformation in tension. The digital image correlation (DIC) is used to capture the surface strain. The DIC results show that the deformation localization occurs in the post-yield strain softening region. The quenched and annealed polymers exhibit different localization types, representing as necking for quenched polymers and shear banding for annealed polymers.
