statement of problem: low- fusing compound (type 1) is used for border molding and impressions. flow and reproducibility of surface detail are two important characteristics of these materials. there are no valid data available comparing domestic and imported brands. purpose: the purpose of this study was to evaluate these two properties of four different products including kerr (kerr manufactur...

Abstract The structure and mobility of dislocations in the layered semiconductor InSe is studied within a multiscale approach based on generalized Peierls–Nabarro model with material-specific parametrization derived from first principles. plasticity turns out to be attributed peculiarities stacking fault relief for interlayer dislocation slips such as existence very low energy barriers. Our res...

One of the new research fields in plasticity is related to choosing a proper non-associated flow rule (NAFR), instead of the associated one (AFR), to predict the experimental results more accurately. The idea of the current research is derived from combining von Mises and Tresca criteria in the places of yield and plastic potential surfaces in rate-independent plasticity.  This idea is implemen...

The discrimination of temporal information in acoustic inputs is a crucial aspect of auditory perception, yet very few studies have focused on auditory perceptual learning of timing properties and associated plasticity in adult auditory cortex. Here, we trained participants on a temporal discrimination task. The main task used a base stimulus (four tones separated by intervals of 200 ms) that h...

In article number 2100059, Junsheng Wang and co-workers report that the heterophase interfaces in Al-Li alloys show generalized stacking fault energy (GSFE) decreasing from middle of δ'-Al3Li/θ'-Al2Cu/δ'-Al3Li composite structures to edge, leading interplanar slip along [001] direction at relatively low shear stress. This interface-mediated plasticity within ultrafine δ'/θ'/δ' precipitate is ex...

A crystal plasticity-based constitutive model is developed to describe the thermomechanical behavior of pseudoelastic NiTi single crystal. The includes, for first time in literature, all inelastic mechanisms influencing fatigue SMAs a finite strain framework: martensite transformation, deformation slip austenite at high-temperature, twinning large strain, transformation-induced plasticity (TRIP...

• Influence of plastic material properties on fracture resistance parameter is analyzed. Mechanism-based strain-gradient plasticity theory, Taylor dislocation model are used. Amplitude and stress intensity factors for strain gradient formulated. Behavior SIFs differs significantly from HRR solution. The crack tip mechanics solids investigated analytically numerically. A first-order mechanism-ba...
