Experimental Study on the Dynamic Tensile Characteristics of Coal Samples
ACS Omega, 2023 As coal mines continue deep mining, the frequency of coal and rock dynamic disasters has also gradually increased. In this paper, dynamic tensile strength deformation, energy evolution, and crack development under an impact test were studied on Brazilian coal samples, using a split Hopkinson pressure bar (SHPB) test device.

Tensile Test For Arboform Samples [PDF]
ACTA Universitatis Cibiniensis, 2015 Abstract Petroleum-based plastic materials constitute a major environmental problem due to their low biodegradability and accumulation in various environments. Therefore, searching for novel biodegradable plastics is received particular attention.

Modeling and Analysing the Tensile Behavior of Fabric Samples
Acta Polytechnica Hungarica, 2013 This paper presents a structural-mechanical model for describing the tensile behavior of textile fabrics in main directions based on the fiber-bundle-cells modeling theory and method. The applicability of this model, created by a variable transformed E-bundle shifted along the deformation axis, was demonstrated by analyzing the tensile load-deformation

Numerical tensile test on a mushy zone sample [PDF]
IOP Conference Series: Materials Science and Engineering, 2012 Time sequences of 3D images of an Al-Cu alloy in the mushy state are obtained using in situ and real-time X-ray microtomography during a tensile test. Surface meshes of phase interfaces are built from these images with the help of a Marching Cubes algorithm.

Tensile-Tearing Fracture Analysis of U-Notched Spruce Samples
Materials, 2022 Spruce wood (Picea Mariana) is a highly orthotropic material whose fracture behavior in the presence of U-shaped notches and under combined tensile-tearing loading (so-called mixed-mode I/III loading) is analyzed in this work. Thus, several tests are carried out on U-notched samples with different notch tip radii (1 mm, 2 mm, and 4 mm) under various ...

Origin of tensile strength of a woven sample cut in bias directions [PDF]
Royal Society Open Science, 2015 Textile fabrics are highly anisotropic, so that their mechanical properties including strengths are a function of direction. An extreme case is when a woven fabric sample is cut in such a way where the bias angle and hence the tension loading direction is around 45° relative to the principal directions.

The effect of postmastectomy radiation therapy on breast implants. Material analysis on silicone and polyurethane prosthesis [PDF]
, 2018 The pathogenic mechanism underlying capsular contracture is still unknown. It is certainly a multifactorial process, resulting from human body reaction, biofilm activation, bacteremic seeding, or silicone exposure.

Compressive and tensile axial strain reduced critical currents in Bi-2212 conductors [PDF]
, 1995 Mono and multifilamentary wires of BSCCO-2212 in Ag matrix are investigated in an axial strain experiment. The superconducting samples are soldered to a substrate that is bend in order to achieve a compressive or tensile axial strain. The I/sub c/-strain
