In materials science, the Charpy impact test, also known as the Charpy V-notch test, is a standardized high strain rate test which determines the amount of energy absorbed by a material during fracture. Absorbed energy is a measure of the material's notch toughness. It is widely used in industry, since it is easy to prepare and conduct and ...
There are several types of test used to measure fracture toughness of materials, which generally utilise a notched specimen in one of various configurations. A widely utilized standardized test method is the Charpy impact test whereby a sample with a V-notch or a U-notch is subjected to impact from behind the notch. Also widely used are crack ...
Often measured with the Izod impact strength test or Charpy impact test, both of which measure the impact energy required to fracture a sample. Volume, modulus of elasticity, distribution of forces, and yield strength affect the impact strength of a material. In order for a material or object to have a high impact strength, the stresses must be ...
Water pressure acting in the pore spaces, fractures or other discontinuities in the materials that make up the pit slope will reduce the strength of those materials. [6] Choice of correct analysis technique depends on both site conditions and the potential mode of failure, with careful consideration being given to the varying strengths ...
The Universal Soil Loss Equation (USLE) is a widely used mathematical model that describes soil erosion processes. [1]Erosion models play critical roles in soil and water resource conservation and nonpoint source pollution assessments, including: sediment load assessment and inventory, conservation planning and design for sediment control, and for the advancement of scientific understanding.
where is the equivalent stress, is the pressure, is the pre-consolidation pressure, and is the slope of the critical state line in space. The pre-consolidation pressure evolves as the void ratio ( e {\displaystyle e} ) (and therefore the specific volume v {\displaystyle v} ) of the soil changes.
Augustin Georges Albert Charpy (1 September 1865 – 25 November 1945) was the French scientist who created the Charpy impact test. He attended École Polytechnique from 1885 to 1887 and graduated with a degree in Marine Artillery. In 1887 he became a professor at École Monge. In 1892 he published his physics thesis.
