CELLULAR TECHNOLOGY: Viscoplastic creep in solder joints where plastic flow appears after about 40 s of the thermal loading. The Material Library is utilized to provide temperature-dependent material properties for the model.
COMSOL Multiphysics gives you complete control over definitions and use of your material properties through the Model Builder and Material Browser. The Material Browser allows you to manage all your model’s materials in one place, and can be complemented by the Material Library. This contains data for 2500 materials including the elements, minerals, metal alloys, thermal insulators, semiconductors, and piezoelectric materials.
Each material is represented by referenced property functions for as many as 24 key properties, dependent on some variable, typically temperature. You can plot and inspect these function definitions, as well as change and add to them. They can then be used in any coupling to other physics simulations that also depend on the property function variable in your multiphysics modeling.
