A hybrid approach for predicting fatigue life of fiber-reinforced polypropylene composite (PPGF40): Integrating micromechanical modelling

Composites Part C: Open Access
This paper presents a hybrid approach for predicting the fatigue life of PPGF40. The approach combines micromechanical modeling with empirical techniques, based on an intrinsic relationship.

Micromechanical Modelling of Size Effects in Microforming

Procedia Engineering, 2017
Abstract This paper deals with the micromechanical modelling of the size dependent mechanical response of polycrystalline metallic materials at micron scale through a strain gradient crystal plasticity framework. The model is implemented into a Finite Element software as a coupled implicit user element subroutine where the plastic slip and ...

Concrete modeling using micromechanical multiphase models and multiscale analysis

Revista IBRACON de Estruturas e Materiais, 2023
: Concrete in its macrostructure is a multiphase cementitious composite material, however, by reducing its scale, it is possible to identify the phases that compose it, among the phases are those embedded in the microscale: the hydrated silicates, in the

Micromechanical modeling of ferroelectric films

Journal of Materials Research, 2005
Ferroelectric films are growing in significance as non-volatile memory devices, sensors, and microactuators. The stress state of the film, induced by processing or constraints such as the substrate, strongly affects device behavior. Thus, it is important to be able to model the coupled and constrained behavior of film material.

Plastically-driven variation of elastic stiffness in green bodies during powder compaction. Part II: Micromechanical modelling

, 2015
A micromechanical approach is set-up to analyse the increase in elastic stiffness related to development of plastic deformation (the elastoplastic coupling concept) occurring during the compaction of a ceramic powder.

Tensile strained $In_{x}Ga_{1-x}P$ membranes for cavity optomechanics [PDF]

, 2014
We investigate the optomechanical properties of tensile-strained ternary InGaP nanomembranes grown on GaAs. This material system combines the benefits of highly strained membranes based on stoichiometric silicon nitride, with the unique properties of ...
