Young’s modulus, also known as the modulus of elasticity, is a crucial material property that defines the stiffness of a ...

Points on the stress curve before full contact is achieved are determined according to Equation 1 and Equation 6 for strain and stress, respectively. The yield point is defined as the point of ...

This article talks about measuring stress-strain curves for shale rock by dynamic instrumented indentation using the nano Ind. ... we were able to estimate the four parameters needed to describe each ...

It is mainly suitable for testing at slow strain rates as it is not sensitive to thermal drift. The insensitivity to drift is obtained by means of measuring displacement and contact area. This is ...

Some materials have a non-linear relationship between stress and strain, a behavior exhibited by materials such as a rubber. These are nonlinear elastic materials for which the slope of the ...

The effective elastic modulus of the matrix then drops to the local slope of the matrix stress/strain curve, (ds M / de) ... The composite continues to deform along the matrix stress/strain curve ...

The physical properties of materials are usually represented by a stress-strain curve and knowledge of the stress-strain curve allows engineers to compare different materials, and predict the behavior ...

This was present through obtained stress-strain plots and RFDA measurements. As well as Young’s modulus measurements, part of the project looked into observing TiB2 particles in a steel matrix.
