Cycle Testing 101

Interface 101 series highlights cycle testing, which uses load cells, torque transducers, and multi-axis sensors to evaluate functional reliability, kinematic wear, seal integrity, switch actuation life, joint loosening, and mechanical degradation across hundreds, thousands, or millions of operating cycles. Cycle testing is an evaluation methodology used to verify product endurance, track mechanical wear, and establish operational life expectancy under repetitive dynamic loading.

What Is the Difference Between Fatigue and Impact Testing?

Interface Tech Talk details why fatigue testing and impact testing are fundamentally different mechanical test methodologies that impose separate physical and electronic demands on measurement hardware. Learn about application differences, load cell and sensor selection, and instrumentation requirements for each type of test.
Fatigue Life Prediction

Fundamentals of Fatigue Life Prediction

Interface load cells accurately quantify the forces applied during fatigue testing for predicting failure. Fatigue refers to the weakening of material caused by repeatedly applied loads. Failure occurs after a certain number of cycles, even when the stresses are well below the material's ultimate tensile strength. While an accurate prediction of fatigue life is not a reality, theoretical analysis and empirical data allow for useful approximations to estimate the margin of safety for a given design.

Load Cells Built for Stress Testing

Interface load cells are designed and manufactured for stress testing. Stress testing with load cells is an integral part of research, design, and manufacturing processes for various products and components. It helps to ensure that material, equipment, and final products can withstand the stresses they will be subjected to in regular use.
