Application of the Double Approximation Method for Constructing Stiffness Matrices of Volumetric Finite Elements
Published 2023-12-01Get full textIntroduction. When numerically solving problems of elasticity theory in a three-dimensional formulation by the finite element method, finite elements (FE) in the form of parallelepipeds, prisms and tetrahedra are used. Regularly, the construction of stiffness matrices of volumetric FE is based on th...

Numerical simulation of the behavior of kinematically unstable slopes under dynamic influences
Published 2022-01-01Get full textIntroduction. The concept of estimating the dynamic parameters of the “base — weakened layer — block” system is proposed, taking into account the physical nonlinearity of the material and the kinematic method of excitation of vibrations. In accordance with this approach, the physical nonlinearity of...

Study of energy transfer processes between rare earth ions and photosensitizer molecules for photodynamic therapy with IR-excitation
Published 2022-02-01Get full textToday, photodynamic therapy is one of the most promising minimally invasive methods of treatment of various diseases, including cancer. The main limitation of this method is the insufficient penetration into the tissue of laser radiation used to activate photosensitizer molecules, which makes it dif...
