Finite Element Method for Simulating the Vickers Hardness Test

Applied Mechanics and Materials, 2014
The purpose of the present paper is to present a different approach to the finite element modeling of the Vickers hardness test measurement, and to establish a numerical correlation between the Young modulus of a material and its hardness. In order to realize this, calculations were based upon the tensions acquired as a result of the hollow caused in ...

Indentation Image Analysis for Vickers Hardness Testing

2018 15th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE), 2018
The paper presents a novel algorithm for detection and measurement of indentations in Vickers hardness testing images, within a specific case of applied research on material quality evaluation based on image processing. The algorithm performs image segmentation by binarization, morphological filtering, and region growing, where the binarization ...

On the representative strain in Vickers hardness testing of 7010 aluminum alloy

Materials Science and Engineering: A, 2015
Abstract A review of the concept of representative strain in Vickers hardness testing is provided and different values reported in the literature are summarized. A new criterion for the proper selection of the representative strain is introduced. By using this criterion, the stress–strain curves of 63 specimens excised from a 7010 aluminum alloy ...

Automatic Vickers Hardness Measurement With Neural Network Segmentation

IEEE Transactions on Instrumentation and Measurement, 2023
The Vickers hardness test is widely used for metal materials. The hardness given by the test is inversely proportional to the ratio of the test force to the indentation area. Since it is inconvenient to measure the area of the indentation manually, it is
