This article presents a simple natural frequency analysis performed with JuliaFEM - an open-source finite element method program. The results are compared with the analysis results pruduced with a commercial software. The comparison shows that the calculation results between the two programs do not differ significantly.

The assessment of the stability of implants in cancellous bone remains a clinical problem. It has been shown that orthopaedic screw fixation depends on the microstructure and orientation of the trabeculae. In the current study we have investigated the possibility of using natural frequency analysis as a means of ranking screw fixation in cancellous bone. A dynamic modal analysis has been completed using the finite element method as a means of measuring implant frequency in a simple description of cancellous bone. A range of impulse excitation values have been examined which lead to implant resonance in different cancellous bone architectures. These values are reported in order that the eventual provision of a clinical diagnostic tool may correctly assess frequency values from the applied impulse.

the article presents the principles and algorithms of the finite element method in solving geotechnical prob-lems taking into account seismic impacts for determining the stress-strain state of structures and slope stabil-ity, implemented in the Midas GTS NX software package. GTS NX allows you to perform calculations of various types of geotechnical problems and solve complex geotechnical problems in a single software envi-ronment. GTS NX covers the entire range of engineering and geotechnical projects, including calculations of the "base-structure" system, deep pits with various mounting options, tunnels of complex shape, consolida-tion and filtration calculations, as well as calculations for dynamic actions and stability calculations. At the same time, all types of calculations in GTS NX can be performed both in 2D and in 3D. The author does not claim to be the author of the finite element method, but he cannot do without pointing out the basic equa-tions, as this affects the definition of the boundaries of use, the formulation of algorithms for constructing calculation schemes and the analysis of calculation results.
