Acoustic investigations of the steel samples deformation during the tensile
Russian Journal of Nondestructive Testing, 2017The paper presents an experimental study of ultrasonic surface waves propagation in the low carbon steel specimens with different degree of degradation of microstructure and mechanical properties, subjected to tensile deformation. The purpose of this paper is to investigate and analyze the dependence between microstructure, mechanical and acoustic ...

Mount for spectroscopic analysis of samples under sustained tensile stress
Review of Scientific InstrumentsSpectroscopic methods offer valuable insights into the molecular and structural changes induced by stress, but existing techniques are often unable to perform real-time measurements during deformation. A novel solid open mount design is presented that enables spectroscopic investigations of materials under sustained tensile stress while maintaining ...

Fractures and energy of fracture of tensile and impact test samples
Metal Science and Heat Treatment, 19751. The change in the energy of fracture is similar in absolute value for samples of titanium alloy OT-4 subjected to tensile and impact bending tests and varies with the structural condition of the material. 2. The fracture surfaces of samples fractured by different methods are similar and vary with the heat treatment, and not with the ...

Applying two optimization techniques in evaluating tensile strength of granitic samples
Engineering with Computers, 2018The Brazilian tensile strength (BTS) test is the most common method to evaluate the tensile strength in mining and civil engineering projects. This paper aims to employ the genetic algorithm (GA) and particle swarm optimization (PSO) for predicting the BTS. For this work, linear and power equations were considered and their weights were optimized By GA

The Journal of Physical Chemistry B, 2019
Molecular dynamics simulation is used to investigate the mechanical properties of the semiflexible polymer during multiaxial tensile deformations. The multiaxial tensile deformations can be imposed in totally or partially constrained modes. These types of deformations may be observed during the sudden deformation of polymeric material in the areas of ...

Tensile creep and recovery of compression molded polypropylene samples
Polymer Engineering & Science, 1963AbstractA simplified creep apparatus was used to evaluate the creep and recovery of polyethylene and polypropylene. The creep resistance of polypropylene containing as much as 9% n‐heptane (boiling) soluble material is superior to that of linear polyethylene. The lower the boiling n‐heptane soluble content, the better the resistance to creep. The creep

A sample carrier device for tensile characterization of ultra-thin and small biomembrane
2019 International Symposium on Micro-NanoMechatronics and Human Science (MHS), 2019We have previously developed a tensile characterization system of ultra-thin and small biomembrane. In this system, we should align the membrane at the tip of the force sensor clamp having microhole array to fix the membrane sample. Since the throughput of the measurement depends on the alignment time, the method of sample alignment enables us to fix ...
