Effects of Sample Geometry on the Uniaxial Tensile Stress State at the Nanoscale

International Journal for Multiscale Computational Engineering, 2009
Uniaxial compression of micro- and nanopillars is frequently used to elicit plastic size effects in single crystals. Uniaxial tensile experiments on nanoscale materials have the potential to enhance the understanding of the experimentally widely observed strength increase. Furthermore, these experiments allow for investigations into the in-strength and

Comparison of FDM-printed and compression molded tensile samples

Materials Testing, 2020
Abstract Since the processing of plastics by additive manufacturing techniques, for example, fused deposition modeling, has become quite common, it is mainly used for the production of unique pieces for private consumption as well as for prototyping in industry.

An improved method for nondestructive shaping of tensile samples

Journal of Scientific Instruments, 1967
An improved nondeforming method for shaping tensile samples was developed using the principle of an immiscible layer electrolytic cell. The polishing apparatus produced samples which were dimensionally accurate, had uniform strain free surfaces, and were not undercut at the sample shoulders.

Acoustic investigations of the steel samples deformation during the tensile

Russian Journal of Nondestructive Testing, 2017
The 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 ...

Stress Distribution in the Sample Neck during the Tensile Testing

2011
In this chapter, the considered issue is presented on the base of two different models of plasticity theory and the detailed derivation of formulae for the average normalised axial stress in the minimal section plane is shown based on different classical approaches.

Mount for spectroscopic analysis of samples under sustained tensile stress

Review of Scientific Instruments
Spectroscopic 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, 1975
1. 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, 2018
The 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
