Tensile testing is common when calculating a stress-strain curve which can determine the yield strength and ultimate strength of a specific test specimen. Tensile testing on a composite specimen The specimen is stretched slowly in tension until it breaks, while the load and the distance across the gage length are continuously monitored.

The yield strength or yield stress is a material property and is the stress corresponding to the yield point at which the material begins to deform plastically. The yield strength is often used to determine the maximum allowable load in a mechanical component, since it represents the upper limit to forces that can be applied without producing permanent deformation. In some materials, such as .
With high surface energy, PLA has easy printability which makes it widely used in 3-D printing. The tensile strength for 3-D printed PLA was previously determined. There is also poly L-lactide-co-D,L-lactide PLDLLA – used as PLDLLA/TCP scaffolds for bone engineering. Solvent welding. PLA can be solvent welded using dichloromethane.
The scrim supports the coating which is initially applied in liquid form and provides the tensile strength, elongation, tear strength, and dimensional stability of the resulting fabric. Vinyl-coated polyester is manufactured in large panels by heat-sealing an over-lap seam with either a radio-frequency welder or a hot-air sealer. A proper seam will be able to carry the load requirements for .
The flexural strength would be the same as the tensile strength if the material were homogeneous. In fact, most materials have small or large defects in them which act to concentrate the stresses locally, effectively causing a localized weakness. When a material is bent only the extreme fibers are at the largest stress so, if those fibers are free from defects, the flexural strength will be .
