THE EFFECT OF STIFFNESS OF THE LOADING SYSTEM ON DETERMINATION OF TENSILE CHARACTERISTICS FROM THE RESULTS OF SMALL PUNCH TESTS

Acta Metallurgica Slovaca, 2014
The assessment of the residual lifetime of critical components of industrial plants requires the knowledge of mechanical properties prior to operation, respecting all technological operations realized throughout the manufacture of the component, and the ...

The Direct Impact Method for Studying Dynamic Behavior of ‎Viscoplastic Materials [PDF]

Journal of Applied and Computational Mechanics, 2022
This work is devoted to the direct impact method for determining the deformation diagrams of viscoplastic materials at high strain rates. As the conventional Split Hopkinson Pressure Bar method, the direct impact method is based on the measuring bar ...

Aggregate Structures and Solid-Liquid Separation Processes

KONA Powder and Particle Journal, 2014
Solid-liquid separation processes for dispersions of fine particles continue to present significant challenges in many areas. As an example, in filtration it is usually possible to achieve either fast filtration or a

Yield stress in amorphous solids: A mode-coupling theory analysis [PDF]

, 2013
The yield stress is a defining feature of amorphous materials which is difficult to analyze theoretically, because it stems from the strongly non-linear response of an arrested solid to an applied deformation.

Conditional QTL Analysis and Fine Mapping for Thousand-Kernel Weight in Common Wheat

Plants
To elucidate the genetic basis of thousand-kernel weight (TKW) related to fundamental traits such as kernel length (KL), kernel width (KW), and kernel diameter ratio (KDR) at the individual quantitative trait loci (QTL) level, both unconditional QTL ...

No yield stress required: Stress-activated flow in simple yield-stress fluids

Journal of Rheology
An elastoviscoplastic constitutive equation is proposed to describe both the elastic and rate-dependent plastic deformation behavior of Carbopol® dispersions, commonly used to study yield-stress fluids. The model, a variant of the nonlinear Maxwell model with stress-dependent relaxation time, eliminates the need for a separate Herschel–Bulkley yield ...

Dynamic yield stresses of glasses: asymptotic formulae [PDF]

Journal of Physics: Condensed Matter, 2005
The stationary, shear rate dependent flow curves of yielding glasses are discussed within a mode coupling theory approach. Asymptotic formulae fo rt he shear stress at the transition point are obtained that take the form of generalized Hershel–Bulkeley constitutive equations, and enable one to find dynamical yield stresses by extrapolation.

Size effects in dislocation depinning models for plastic yield

, 2013
Typically, the plastic yield stress of a sample is determined from a stress-strain curve by defining a yield strain and reading off the stress required to attain it.
