Linearization According to the K-type Ascent Research Principle

The mechanics of the process of setting the line and plotting linearized stresses. When choosing a reference line, the program determines the stress components along this line and additionally performs a linearization procedure on these components - allocation of membrane, bending and nonlinear stresses. By linearized components the sums of membrane and bending are determined.

A description of the linearization process can be studied in this section.
