DEVELOPMENT OF THE STIFFNESS MATRIX OF A PHYSICALLY NONLINEAR FINITE ELEMENT WITH A COMPOSITE STRUCTURE
It is known that the carrying capacity of ice can be significantly increased by the introduction of reinforcing elements. The paper proposes a mathematical model of the stiffness matrix for a composite finite element that combines the joint work of two or more materials. The obtained dependences, dependences can be applied in the calculation of structural elements taking into account their reinforcement. The proposed approximating functions for the deformation diagrams. The algorithm of composite material destruction presented in the form of a block diagram is proposed.
