Time varying stress model

[pantagruel]

Hello,

Can everyone explain me if in Alta 6 pro time varying stress model formulation is valid for several stresses (such as temeprature, voltage, humidity...) .
Is cumulative damage model valid only for one stress ?
Please help
Many thanks
Regards

Pantagruel, Currently ALTA 6 supports a single time-varying stress using either an exponential or power model (i.e. it could be temp, hum, or voltage alone). It does not support multiple simultaneously and independently time varying stresses. Our R&D group is looking at expanding this in future versions.
