[AFM-MA・DMA] Mechanical Property Evaluation (Elastic Modulus and Dynamic Viscoelasticity)
AFM-MA and AFM-DMA are analyses that can provide insights into hardness.
Fitting is performed using various computational models on the force curve, which is an AFM measurement technique, to obtain elastic and viscoelastic data. ? Data can be measured in micro-regions that are consistent with DMA testing machines and nanoindenters. ? Applicable to materials with various hardness ranging from 10 kPa to 100 GPa. ? Fitting is possible using elastic models (DMT, Hertz, JKR) and viscoelastic models. ? Elastic modulus and viscoelastic modulus mapping can be performed using the above models. ? Frequency dependence (0.1 to 20 kHz) can be evaluated at each analysis point. ? Measurements can be conducted with temperature changes (room temperature to 250°C).
