Tensile
Tensile Testing of Metals is a destructive test process that provides information about behavior of the material. Mechanical properties can be derived from the Load / displacement or Stress / Strain curves:
- Yield Strength / Yield Point (YS)
- Ultimate Tensile Strength (UTS)
- Youngs Modulus for elasticity
- Modulus of Toughness - Brittleness
- Elongation and reduction in area – Ductility

Impact
Various type of notched-bar impact tests are used to determine the tendency of material to behave in a brittle manner. The impact test is performed at various temperatures to uncover any effects on impact energy. The charpy impact testing methods, including the charpy V-notch test and weld charpy test. The ASTM impact test methods are regularly performed. Testing can be accomplished at temperatures in the range of -196ºC to 25ºC with an impact energy up to 320 ft. lbs.

Bending
A bend test measures the ductility of a material by bending it over a given radius. On completion of the test the coupon is examined for defects that may have opened up on the tension face.
Classification by bending samples
Face bend tests - made with the weld face in tension. Reveals defects on the face such as excessive undercut or lack of sidewall fusion close to the cap.
Root bend tests - made with the weld root in tension. Reveals lack of root fusion or penetration.
Side bend test – made with the weld cross section in tension. Reveals lack of side-wall fusion and lack of root fusion in double-V butt joints.

Hardness (Vickers/Rockwell/Brinell)
The hardness of a material usually is considered as the resistance to deformation and for metals the property is a measure of their resistance to permanent or plastic deformation.
There are a number of test methods:
Vickers Hardness Test
Vickers testing machines have a microscope or USB camera to visualize and measure the indentation caused on a test sample by a diamond indenter. The indenter is an upside-down pyramid shape with a square base and an angle of 136 degrees between opposite faces.
