Three samples of shale rock, two from the Eagle Ford play and one from the Haynesville play, were successfully tested by instrumented indentation using a Nano Indenter G200 from KLA. Results were ...

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 ...

Stress-strain curve and dislocation configuration/evolution in MPEAs. (A) is a diagram of DDD simulations for MPEAs. Video showing the effect of lattice strain field on the dynamic evolution of ...

This image shows comparisons of true stress-strain curve for Al between the calculated and experimental results at different temperatures. (a) Low temperature; (b) high temperature.

The traditional method for determining yield stress on a rotational rheometer or viscometer was by fitting models to the measured rheograms and extrapolating to zero shear rate. This article discusses ...

A neck is formed in a tensile test specimen when the UTS of the engineering stress/strain curve is reached. Prior to this stress-strain condition the plastic deformation occurs throughout the sample ...

The tensile behavior of composites is also different from that of metals in the 'plastic deformation' region of the stress/strain curve. The diagram shows the curve for a uniaxial sample tested along ...

Thermal and mechanical stresses are creating significant challenges in heterogeneous chiplet assemblies, increasing the time and cost required to work through all the possible physical effects, ...

Introduction to Mechanical Properties provides a thorough introduction to key mechanical properties, such as tensile strength, hardness, ductility, and impact resistance. This class discusses how ...

Strain measurement is imperative during prototype design and testing. Measuring strain ensures that materials perform as they should and that equipment is safe, functional, and durable. The resistive ...
