Webb5 juni 2012 · In continuum mechanics, the physical properties of a continuum ( field properties) are described by field variables such as pressure, temperature, density, velocity, etc. There are three major types of field variables: tensors (e.g. stress, strain, strain rate). Field variables can be represented in a fully continuous manner (analytical ...
