In the field of road safety and vehicle occupant protection, pulling tests on seat belts can even save lives.
Whether textiles, cast and forged products, sheet metal and rod material – the tensile test on the tensile testing machine is a standardized method of material testing with which we determine the yield point, tensile strength, elongation at break, modulus of elasticity and other material parameters. These determined characteristic values
In addition to hardness tests, tensile tests are one of the most frequently performed test methods in mechanical materials testing.
In tensile tests, we determine, for example, what load a material can withstand until it begins to deform plastically (yield point) or under what maximum load the material tears (tensile strength). In the tensile test, we also determine what elongation the material shows after breaking (elongation at break) in order to obtain information about the toughness of a material.
To carry out the tensile test, a sample (e.g. round tensile test, flat tensile test, shoulder bar) is firmly clamped in the tensile testing machine. The sample is then placed under tensile stress in that the clamping jaws are raised slowly and smoothly. This process continues until the specimen breaks. During the entire process, a load cell measures the force level and the change in length of the tension rod using a precision extensometer. The result is a force-strain curve specific to each material.
With a wide range of tensile tests, we help you to quickly and reliably answer questions about quality, safety and economic efficiency and also to solve complex tasks. This includes the implementation of standard tensile tests on standard test specimens as well as the development of non-standardized test methods on components as well as test set-ups and devices for solving special problems in direct customer contact.
