A Phase‐Field Model for Quasi‐Dynamic Rupture Nucleation and Propagation of In‐Plane Faults

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Computational modeling of faulting processes is an essential tool for understanding earthquake mechanics but remains challenging due to the structural and material complexities of fault zones. The phase‐field method has recently enabled unified modeling of fault propagation and off‐fault damage within a fracture‐mechanics‐based framework ...

Modeling the Elastic Recovery of PET Bottles via a Free‐Blowing of Preforms Campaign

Polymer Engineering &Science, EarlyView.
From free‐blown preforms to mechanical properties. ABSTRACT This study aims to quantify the elastic properties induced by biaxial stretching at different temperatures in order to simulate the complete process including the final elastic recovery. The elastic modulus is identified from geometric measurements obtained during free‐blowing experiments. PET

Moisture Absorption in Highly Porous Closed‐Cell Polymeric Foams

Polymer Engineering &Science, EarlyView.
The conventional one‐dimensional hindered diffusion model has been extended into a new Void Filling Hindered Diffusion Model. By quantifying the moisture stored within closed‐cell pores, this model successfully captures the distinct absorption behaviors observed across varying foam thicknesses.

Homogenization and uniform stabilization for a nonlinear hyperbolic equation in domains with holes of small capacity

Electronic Journal of Differential Equations, 2004
In this article we study the homogenization and uniform decay of the nonlinear hyperbolic equation $$ partial_{tt} u_{varepsilon} -Delta u_{varepsilon} +F(x,t,partial_t u_{varepsilon}, abla u_{varepsilon})=0 quadhbox{in }Omega_{varepsilon}imes(0,+infty) $

Size effects for micro-fractured bodies under compressive loading [PDF]

Theoretical and Applied Mechanics, 2011
A two-scale damage model for micro-fractured media is constructed using the asymptotic homogenization method. At the small-scale level, we consider locally periodic microstructures of two-types: micro-cracks nucleating from pores and wing-type micro ...

Host resistance modulates in planta efficacy of seed‐applied fluxapyroxad against spot form net blotch in barley

Pest Management Science, EarlyView.
Barley variety influences fluxapyroxad efficacy by affecting distribution and dissipation of the active ingredient, with plant biomass contributing to these differences. Abstract BACKGROUND Seed‐applied fungicides are used to protect barley seedlings from spot form net blotch, caused by Pyrenophora teres f. maculata, among other diseases.

Characterization of a novel R98Q mutation that confers resistance to sulfentrazone in common ragweed (Ambrosia artemisiifolia) populations from Michigan

Pest Management Science, EarlyView.
Field‐collected Ambrosia artemisiifolia populations from Michigan, USA, soybean fields exhibited strong resistance to the protoporphyrinogen IX oxidase (PPO)‐inhibiting herbicide sulfentrazone and reduced sensitivity to fomesafen. Target‐site analysis identified a novel Arg‐98‐Gln (R98Q) substitution in PPO2, co‐occurring with the previously reported ...

Effects of High-Pressure Homogenization on the Structural, Physical, and Rheological Properties of Lily Pulp

Foods, 2019
The effects of high-pressure homogenization (HPH) on the structural, physical, and rheological properties of lily pulp (15%, w/w) were investigated. Different pressures ranging from 0 MPa to 100 MPa were used.

Wildfire Ash Alters Freshwater Crustacean Behavior: Disentangling the Contributions of Suspended Macroparticles and Ash‐Induced Alkalinization

Environmental Toxicology, EarlyView.
ABSTRACT Climate change and anthropogenic ignitions are intensifying wildfire frequency worldwide, elevating the risk of freshwater contamination by ash. In water, dissolved ash releases ions and other toxic constituents that increase pH and alter physicochemical conditions, while suspended ash particles may impose mechanical stress, disrupt behavior ...

Stochastic homogenization of rate-dependent models of monotone type in plasticity [PDF]

, 2019
In this work we deal with the stochastic homogenization of the initial boundary value problems of monotone type. The models of monotone type under consideration describe the deformation behaviour of inelastic materials with a microstructure which can be ...
