Also known as the Tensile Impact Test, the Impact Test uses a specimen that is clamped into a pendulum. The test specimen looks like the one shown in Figure 4. The pendulum swings down and strikes the specimen against an anvil breaking the specimen. This test enables the impact energy to be determined for the weld seam and base material.Tensile strength is a measurement of the force required to pull something such as rope, wire, or a structural beam to the point where it breaks.. The tensile strength of a material is the maximum amount of tensile stress that it can take before failure, for example breaking.. There are three typical definitions of tensile strength: Yield strength - The stress a material can withstand .The tensile impact strength test was originally developed to overcome the deficiencies of flexural (both Izod and Charpy) impact test. All the test variables that have a high effect on the results, such as notch sensitivity, toss factor and specimen thickness, are eliminated in the tensile impact test. This test, on the contrary of Izod and

The flexural strength is stress at failure in bending. It is equal to or slightly larger than the failure stress in tension. Flexural strength, also known as modulus of rupture, or bend strength, or transverse rupture strength is a material property, defined as the stress in a material just before it yields in a flexure test. [1] The transverse bending test is most frequently employed, in .Tensile test of an Al-Mg-Si alloy.The local necking and the cup and cone fracture surfaces are typical for ductile metals.

In materials science, a triaxial shear test is a common method to measure the mechanical properties of many deformable solids, especially soil (e.g., sand, clay) and rock, and other granular materials or powders. There are several variations on the test.In materials science, hardness (antonym: softness) is a measure of the resistance to localized plastic deformation, such as an indentation (over an area) or a scratch (linear), induced mechanically either by pressing or abrasion.In general, different materials differ in their hardness; for example hard metals such as titanium and beryllium are harder than soft metals such as .

In materials science, creep (sometimes called cold flow) is the tendency of a solid material to undergo slow deformation while subject to persistent mechanical stresses.It can occur as a result of long-term exposure to high levels of stress that are still below the yield strength of the material. Creep is more severe in materials that are subjected to heat for long periods and generally .
