A crystal plasticity phenomenological model to capture the non-linear shear response of carbon fibre reinforced composites

International Journal of Lightweight Materials and Manufacture, 2021
A hardening response is often observed for shear-dominated large deformation of Carbon Fibre Reinforced Plastics (CFRP). This non-linear response is often modelled by fitting a strain hardening law against experimental stress-strain curves. Inspired by a

Generative model‐enhanced human motion prediction

Applied AI Letters, 2022
The task of predicting human motion is complicated by the natural heterogeneity and compositionality of actions, necessitating robustness to distributional shifts as far as out‐of‐distribution (OoD).

Drought-hardening improves drought tolerance in Nicotiana tabacum at physiological, biochemical, and molecular levels

BMC Plant Biology, 2020
Background Drought stress is the most harmful one among other abiotic stresses with negative impacts on crop growth and development. Drought-hardening is a feasible and widely used method in tobacco seedlings cultivation.
