Abstract:
Durability is the ability of a product or material to perform its function at the anticipated performance level over a given period (e.g., number of cycles or hours in use), under the expected service conditions. Polymers, rubbers and composite material parts make up more than 50% of working components in an automobiles, aerospace structures and consumer durables. Endurance, durability & duty cycle testing of polymers thus becomes critical for lifetime prediction of these parts and components.
Durability testing can be classified into the following types:
(a) Weathering & Heat ageing.
(b) Fatigue.
(c) Stability Tests.
(d) Thermal Cycling.
(e) Resistance to Liquids.
(g) Environmental Exposure
To obtain endurance and durability data, rigorous testing of the components is carried out to find out the length of time the product can carry out its function with no damage or degradation. These tests are set up by simulating the conditions that ordinarily develop in the products’ lifespan. Accelerated conditions are then superimposed to quickly ascertain the product and material lifespan. The rigorous testing simulators can test for any contingency that may develop with your product.

Advanced Scientific and Engineering Services (AdvanSES) specializes in endurance and durability testing of materials and components including hoses, engine mounts, vibration isolators, silent bushes etc. Fatigue testing can be carried out in stress & force control, strain control or displacement control. The deformation modes under which fatigue tests are generally carried out are tension – tension, compression – compression, tension – compression and compression – tension.
