Analysis of damage and fracture formulations in cold extrusion [PDF]

open access: yes, 2017
In forming processes, components generally undergo large deformations. This induces the evolution of damage, which can influence material and product properties.

Simulation of Test Arch Based on Concrete Damage Plasticity Model and Damage Evolution Analysis

open access: yesApplied Sciences, 2023
In light of the limited research on latent damages during the construction of large-span suspension arches, this study introduced a method to simulate structural damage utilizing random porosity.

EVOLUTIONAL BUILDING DAMAGE PREDICTION

open access: yesJournal of Structural and Construction Engineering (Transactions of AIJ), 2009
We hypothesized that the scale of the predicted Nankai Earthquake will increase gradually year by year as the time passes from the last occurrence in December 1946, and then we estimated strong motions chronologically from 2009 to 2060 for western Japan based on the up-to-date strong motion prediction method, i.e., the so-called statistical Green's ...

Modeling of ductile damage using numerical analyses on the micro-scale [PDF]

open access: yes, 2013
The presentation deals with a continuum damage model which has been generalized to take into account the effect of stress state on damage criteria as well as on evolution equations of damage strains.

Damage evolution in marble under uniaxial compression monitored by Pressure Stimulated Currents and Acoustic Emissions

open access: yesFracture and Structural Integrity, 2019
The spatiotemporal evolution of damage in marble speci¬mens under uniaxial compression is monitored using Pressure Stimulated Currents (PSCs) and Acoustic Emissions (AEs). The novelty of the study is the use of an integrated grid of sensors (instead of a

Imaging Studies of photodamage and self-healing in disperse orange 11 dye-doped PMMA

open access: yes, 2011
We report on optical imaging studies of self-healing after laser-induced photodamage in disperse orange 11 dye doped into poly(methyl methacrylate) (PMMA) polymer.

Determination of a set of constitutive equations for an al-li alloy at SPF conditions [PDF]

open access: yes, 2015
© 2015 The Authors.Uniaxial tensile tests of aluminium-lithium alloy AA1420wereconducted at superplastic forming conditions. The mechanical properties of this Al-Li alloy were then modelled by a set of physicallybased constitutive equations.

Damage Spreading in the Ising Model

open access: yes, 1997
We present two new results regarding damage spreading in ferromagnetic Ising models. First, we show that a damage spreading transition can occur in an Ising chain that evolves in contact with a thermal reservoir.

A degenerating PDE system for phase transitions and damage [PDF]

open access: yes, 2013
In this paper, we analyze a PDE system arising in the modeling of phase transition and damage phenomena in thermoviscoelastic materials. The resulting evolution equations in the unknowns \theta (absolute temperature), u (displacement), and \chi (phase ...

Local Monte Carlo Method for Fatigue Analysis of Coarse-Grained Metals with a Nanograined Surface Layer

open access: yesMetals, 2018
The fatigue resistance of coarse-grained (CG) metals can be greatly improved by introducing a nanograined surface layer. In this study, the Weibull distribution is used to characterize the spatially-random fracture properties of specimens under axial ...
