Plastic Tensile Testing

Tensile modulus how much a material can deform stretch in response to stress before it yields.

Plastic tensile testing.

The figure below from quadrant engineering plastic products shows the test geometry. Achieving reliable results in tensile testing of plastics automotive and medical applications increasingly call for tighter tolerances requiring suppliers to perform their own testing. Elongation at yield the ratio between increased length and initial length at the yield point. Cut or injection mold your material into one of the five dumbbell shapes.

Astm d638 tensile testing of plastics 1. The test is conducted at tensile rates ranging from 1 to 500 mm min until the specimen fails yields or breaks. How to perform a tensile test on plastics according to iso 527 2. Iso 527 2 is performed on a universal testing machine by applying a tensile force to a sample specimen and measuring various properties of the specimen material under stress.

Tensile testing is commonly used and represents an integral input to quality control. How to perform an astm d638 plastic tensile strength test test procedure. The exact shape you use is. Needs to be servo controlled to keep a constant rate of speed.

Tensile strength the maximum amount of tensile stress that a material can withstand before failure through a. For this test plastic samples are either machined from stock shapes or injection molded. Test types tensile strength the amount of force that can be applied to a plastic before it yields stretches irreparably or. Elongation at break the ratio between.
