Creep test low viscosity fluids8/25/2023 A minimum of 20 data points are required to produce a creep rupture plot. From this data, a plot of stress versus log failure time can be generated. A range of applied stresses are used to generate failure times, typically from 100s to 106s. The resulting data is used to calculate the creep modulus.Ĭreep rupture is a measure of failure time as a function of applied stress. Creep strain testing can be carried out in a controlled environment up to temperatures of 80☌. The stress is applied using a lever system with dead weights, and the strain is measured using precision extensometers which allow the strain to be recorded to computer. The experts at the Smithers rubber and plastic testing labs use two different methods to measure creep performance of rubber and polymer materials:Ĭreep strain testing is performed by applying a constant tensile load to the test specimen and measuring the resulting straight in order. Long-term mechanical creep testing is especially valuable for assessing materials with high temperature service applications, such as engines, ovens, and boilers. Smithers Quality Assessments Client PortalĬreep testing is used to measure how a material deforms over time while subjected to constant stress at a constant temperature.
