The entire stress-strain curve can now be determined using nanoindentation with a flat-ended cylindrical punch and novel analysis of the resulting force-displacement data 1. Unlike pyramidal indenters ...
Durability of components under dynamic load can be increased by understanding the origin of the stress and strain distribution. While numerical simulations based on finite element (FE) models can help ...
In Session 23 of the KLA Instruments Indentation University series, nanoindentation measurement of the yield stress-strain curve is demonstrated using the iMicro nanoindenter on Ti-6Al-4V, and ...
Stress is a normal psychological and physical reaction to the demands of life. A small amount of stress can be good, motivating you to perform well. But many challenges daily, such as sitting in traffic, meeting deadlines and paying bills, can push you beyond your ability to cope. Your brain comes ...
Strain Types There are three types of strain: Longitudinal Strain Volume Strain Shear Strain A. Longitudinal Strain This type of strain is called longitudinal strain and occurs when a body is subjected to tensile or compressive stress. It is defined as the ratio of the change in length to the original length of the body.
Therefore, strain is a dimensionless number. Strain under a tensile stress is called tensile strain, strain under bulk stress is called bulk strain (or volume strain), and that caused by shear stress is called shear strain. The greater the stress, the greater the strain; however, the relation between strain and stress does not need to be linear.
