Detailed Description

Base class for stress/strain vector representations. It is derived from FloatArray class, which is used to store the stress/strain vector components in reduced form. Additional attribute is introduced to keep the stress/strain mode. This allows to implement various stress/strain vector methods regarding the correct stress/strain mode without doing so in full form. The full form includes all components, even if they are zero due to stress/strain mode nature, but in the reduced format, only relevant nonzero components are stored. If in particular mode particular stress component is zero, the corresponding strain is not computed and not stored in reduced vector, and in full vector there is zero value on corresponding position. On the other hand, if zero strain component is imposed this condition must be taken into account in geometrical relations (at element level), and corresponding component are included stress/strain reduced vectors. Methods for converting vectors between reduced and full format are provided.
