Progress in Indentation Study of Materials via Both Experimental and Numerical Methods

Abstract: Indentation as a method to characterize materials has a history of more than 117 years. However, to date, it is still the most popular way to measure the mechanical properties of various materials at microscale and nanoscale. This review summarizes the background and the basic principle of processing by indentation. It is demonstrated that indentation is an effective and efficient method to identify mechanical properties, such as hardness, Young's modulus, etc., of materials at smaller scale, when the traditio… Show more

“…As these microstructural processes can, due to highly inhomogeneous amounts of plastic deformation, be locally different in extruded Al tubes, small-scale testing methods are required for analyzing the local mechanical properties. For this, indentation testing can be used, which enables the local characterization of a material's monotonic mechanical properties, i.e., hardness or elastic modulus [12][13][14]. By performing cyclic indentation tests (CITs), the cyclic properties of a material, e.g., the cyclic deformation behavior [15,16] or fatigue crack propagation [17], can also be analyzed.…”

“…A aplicação de procedimentos semi-empíricos na determinação de propriedades de materiais na indentação instrumentada tem ganhado destaque na última década em virtude de possibilitar a determinação de diversas propriedades mecânicas diferentes, tais como: módulo de elasticidade, dureza, tensão de escoamento, expoente de encruamento entre outras, em relação as metodologias empíricas utilizadas comumente para a determinação da dureza e módulo de elasticidade. Resultados recentes destes procedimentos são apresentados por LIU et al [17] onde são discutidos os procedimentos empíricos da indentação instrumentada e os procedimentos que utilizam métodos numéricos para obtenção da curva carga-penetração e as propriedades mecânicas de módulo de elasticidade e dureza. Também, WANG et al [18] mostram o fenômeno da indentação do ponto de vista da nanoescala por meio de uma discussão dos modelos numéricos utilizados para simular o processo entre eles estão a dinâmica molecular, método quase contínuo, dinâmica de deslocamentos discretos e o método de elementos finitos aplicado à plasticidade cristalina.…”

“…In general, indentation tests constitute an efficient method to determine various mechanical properties, such as hardness or elastic modulus [11,12]. Furthermore, a material's cyclic properties can be characterized using cyclic indentation tests (CITs) [13][14][15].…”
