The purpose of this study was to correlate the analytical calculation with FEA to validate the cause of failure and the impact of the viscoelastic property. It aims to understand the linear viscoelastic behavior of Copper-Nickel alloy due to the axial and bending load acting on the cantilever beam. The time-dependent behavior of metals and polymers is due to time, stress, strain, and temperature. This behavior of the material is assumed as linear viscoelastic behavior when there is a small amount of strain. Viscoelastic phenomena such as creep and stress relaxation are common in polymers. A cantilever beam is used here to analyze the viscoelastic behavior, as it is the most common structural part of the connectors such as latch or terminals. The usual method of determining the values in most of the studies is using the Prony series. However, understanding the behavior using basic models like Maxwell is necessary to start with analytical and simulation results correlation and can be applied to the Generalized Maxwell model. Prony series constants are obtained by fitting the test data to the constitutive equation. The correlation is observed in results when a simpler model, cantilever beam under loads like axial and bending loads are applied. Indicating the study can be extended on the assembly level components as well.
