TL;DR: All fundamental stages of the computer process, which accomplishes stress--strain-state computations by the finite-element method (FEM), are related to the formation and processing of a global stiffness matrix (GSM).
Abstract: All fundamental stages of the computer process, which accomplishes stress--strain-state computations by the finite-element method (FEM), are related to the formation and processing of a global stiffness matrix (GSM). Solution of practical problems reduces to GSM of extremely high orders; the method employed to store the GSM in the memory of a computer determines to a significant degree the efficiency of the corresponding software. At the present time, the method of storing GSM in the form of the upper or lower symmetric portion of the band has come into the most widespread use [1-7].
