Abstract:
A laser-based finite element(FEM) method for determination of the complex modulus of visco-elastic material is re-examined in this paper. The parametric sensitivity on FEM inverse algorithm and the applicable scope on material damping are investigated. Measurement of time-temperature superposition (TTS) has been achieved at the developed test systems. The discrepancy is within 10% in comparison with the measured date from a commercial Dynamic Mechanical Analysis (DMA), and this validates the accuracy of the developed test system.
