Temperature Dependent Material Properties

Evaluate a material characterized at multiple temperatures.

**Currently, temperature dependent material properties are only supported for unidirectional composites, not woven composites.

The MCT multiscale material characterization process can be performed using composite material data taken at one or more temperatures. If the MCT characterization is performed at a single temperature, the resulting composite and constituent properties are assumed to be independent of temperature. If the MCT characterization is performed at multiple temperatures, composite and constituent properties are determined separately for each discrete temperature for which composite material data was supplied. In this case, the resulting collection of composite and constituent properties is utilized to linearly interpolate the composite and constituent properties at any given temperature.

The image below illustrates an example case where the MCT characterization process was performed using composite material data taken at three discrete temperatures T1< T2< T3. Here, the vertical axis labeled 'MCT Properties' could represent any composite or constituent property (e.g., moduli, Poisson ratios, coefficients of thermal expansion, strengths, etc.). If the composite material is at temperature T that is between T1 and T3, the composite and constituent properties at T are linearly interpolated from available data. If the composite material is at a temperature T that is less than T1 or greater than T3, we simply use the composite and constituent properties from the closest characterized temperature (T1 or T3).
