Methodical Features of Tensile Testing of Ring Samples
Inorganic Materials: Applied Research, 2020Experimental and computational studies of the deformation behavior of ring samples under stretching with the use of cylindrical supports have been performed. Methodological errors of this type of testing have been analyzed. The deformation accumulated upon straightening a ring sample and also the gauge length thereof depending on the dimensions of the ...

Simulation Analysis of the Tensile Process on Sheet Sample
Applied Mechanics and Materials, 2011Stress-strain is commonly used in engineering; however the real stress-strain is more used in the test and exploitation of new product. ANSYS finite element software is adopted in this study, stress-strain of the tensile sample of the sheet in different stage is calculated under the 10mm displacement load, stress-strain curve is obtained, and the ...

Tensile strength from imperfect samples
Journal of Materials Science Letters, 1988It is often necessary to carry out tensile strength tests on fibre cement composite samples cut from a flat sheet in the as-received condition where further sample preparation is undesirable. Very often the sample coupons show defects such as bowing. These imperfections are most noticeable for materials which fail at low strains, such as some of the ...

Comparison of FDM-printed and compression molded tensile samples
Materials Testing, 2020Abstract 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, 1967An 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, 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 ...

Stress Distribution in the Sample Neck during the Tensile Testing
2011In 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.
