Surface shear-transformation zones in amorphous solids [PDF]

Physical Review E, 2014
We perform a systematic study of the characteristics of shear transformation zones (STZs) that nucleate at free surfaces of two-dimensional amorphous solids subject to tensile loading using two different atomistic simulation methods, the standard athermal, quasistatic (AQ) approach and our recently developed self-learning metabasin escape (SLME) method

Microstructural Shear Localization in Plastic Deformation of Amorphous Solids

, 2001
The shear-transformation-zone (STZ) theory of plastic deformation predicts that sufficiently soft, non-crystalline solids are linearly unstable against forming periodic arrays of microstructural shear bands.

Zein‐Based Adhesives: Sustainable Extraction and Application in Bioadhesive Technologies

Advanced Engineering Materials, EarlyView.
Zein is extracted from corn gluten meal using a simple and scalable process with high yield (~90%). The resulting protein is applied in bioadhesives modified with Ca2+ and Fe3+ ions, exhibiting substrate‐dependent adhesion. The findings demonstrate competitive bonding performance and highlight the role of ionic interactions in tuning adhesion ...

A vector sum analysis method for stability evolution of expansive soil slope considering shear zone damage softening

Journal of Rock Mechanics and Geotechnical Engineering
Slope stability analysis is a classical mechanical problem in geotechnical engineering and engineering geology. It is of great significance to study the stability evolution of expansive soil slopes for engineering construction in expansive soil areas ...

Modeling of temperature distribution in orthogonal cutting with dual-zone contact at rake face [PDF]

, 2012
In this study, an analytical model is developed in order to calculate the temperature distribution in orthogonal cutting with dual-zone contact at the rake face. The study focuses on heat generation at the primary shear zone and at the rake face.

The role of strain localization in magma injection into a transtensional shear zone (Variscan belt, SW Iberia). [PDF]

, 2013
This study deals with the interaction between deformation and magmatism in mid- to deep-crustal domains. The relation is analysed between migmatites and shear zones and the spatial distribution of leucogranitoid veins and dykes running through a footwall

Investigation of Laser Ablation and Brush Pre‐Treatments for AlCu Cold Roll Bonding in Oxygen‐Free Conditions

Advanced Engineering Materials, EarlyView.
It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

Strength characteristics of the sliding zone soil of bedding deep cutting slopes and early warning analysis of the reserved thickness of the base

地质科技通报
Objective Bedding deep cutting slopes containing weak interlayers are commonly found in slope engineering, whose stability is influenced by two key factors: The strength of the sliding zone soil and the reserved thickness of the base (the distance from ...

Analysis of Location of Villages in Relation to Rupture Zone (Case Study: North Qazvin Fault) [PDF]

مسکن و محیط روستا, 2021
This paper studies the shear zone of North Qazvin fault and investigates the location of rural settlements in this area. In selected sections, the presence of transverse valleys along the fault made it possible to investigate the evidence of shear zones ...

Experimental analysis and modeling of orthogonal cutting using material and friction models [PDF]

, 2007
In this study, a process model for orthogonal cutting processes is proposed. The model involves the primary and secondary deformation zones. The primary shear zone is modeled by a Johnson-Cook constitutive relationship and a shear plane having constant ...
