Title: | New relationship between Young's modulus and nonideally sharp indentation parameters | Authors: | Ma, D Ong, CW Wong, SF |
Issue Date: | Jul-2004 | Source: | Journal of materials research, July 2004, v. 19, no. 7, p. 2144-2151 | Abstract: | Both analysis and numerical calculations have been carried out to investigate the relationship between Young's modulus and nonideally sharp indentation parameters. The results confirm that there exists an approximate one-to-one correspondence between the ratio of nominal hardness/reduced Young's modulus (H[sub n]/E[sub r]) and the ratio of elastic work/total work (Wₑ/W) for any definite bluntness ratio (Δh/h[sub m]) of a nonideally sharp indenter. Based on this relationship, the Young's modulus of the indented material can be determined just from the values of H[sub n], Wₑ, and W, which are directly measurable quantities in an indentation test. | Keywords: | Approximation theory Differential equations Elastic moduli Elasticity Hardness Indentation Integral equations Mathematical models Numerical analysis Polynomials |
