How to Calculate UTS
This gives a value in N/mm² or MPa. During a tensile test, the material is pulled until it breaks. The highest recorded force, divided by the original cross-sectional area, gives the UTS. This value is the peak on a stress-strain curve.

What is a three-point bend test?
A three-point bend test is a widely used method for determining the flexural properties of materials. It involves applying a load at the midpoint of a specimen supported at two points, creating a bending force.
