A Review of Microstructural Evolution and Modelling of Aluminium Alloys under Hot Forming Conditions

open access: yesMetals, 2020
Microstructural evolution during hot forming of aluminium alloys plays a critical role in both the material flow behaviour during the deformation and the post-form mechanical properties in service.

Morphology of viscoplastic drop impact on viscoplastic surfaces

open access: yesSoft Matter, 2017
The impact of viscoplastic drops onto viscoplastic substrates characterized by different magnitudes of the yield stress is investigated experimentally. The interaction between viscoplastic drops and surfaces has an important application in additive manufacturing, where a fresh layer of material is deposited on a partially cured or dried layer of the ...

On stress resultant plasticity and viscoplasticity for metal plates [PDF]

open access: yes, 2008
In this work we derive elastoplastic and elastoviscoplastic finite element formulations for stress resultant bending analysis of thin metal plates. The principle of maximum plastic dissipation is used to obtain the ingredients of the small strain stress ...

Viscoelastic-plastic damage creep model for rock

open access: yesYantu gongcheng xuebao, 2020
Based on the classical element model, the nonlinear element and the creep damage are introduced to solve the problem that the classical element model cannot describe the non-linear characteristics of rock during the whole compressive creep process ...

Overstress and flowstress approaches to dynamic viscoplasticity

open access: yesEPJ Web of Conferences, 2015
Viscoplasticity is mostly modelled by the flowstress approach, where the flowstress (Y) is a function of pressure, temperature, plastic strain and strain rate Y(P,T, εp, ε̇).

Damage-property analysis of carbon fiber-reinforced plastic based on homogenization theory

open access: yesMechanical Engineering Journal, 2020
In this study, the damage-development behavior of carbon fiber-reinforced plastic (CFRP) laminates considering the nonlinear mechanical properties of a matrix resin was investigated through a numerical simulation based on a homogenization theory and ...
