    Opis:
    The subject of the research was a undercarriage leg of a gyroplane made of composite materials. The aim of the work was to assess the level of damage initiation of the composite gyroplane undercarriage. In the study, a structural capacity analysis was carried out, taking into account the phenomenon of damage initiation. Numerical calculations were conducted based on the finite element method in the ABAQUS® software. The issue was solved according to the Newton-Raphson algorithm.

    Opis:
    This paper discusses the problem of design optimization for an I-section profile. The optimization process was performed using the Abaqus program. The numerical analysis of a strictly static problem was based on the finite element method. The scope of the analysis involved both determination of stresses and displacements in the profile and structure topology optimization. The main focus of the numerical analysis was put on reducing profile volume while maintaining the same load and similar stresses prior to and after optimization. The solution of the optimization problem is just an example of the potential of using this method in combination with the finite element method in the Abaqus environment. Nowadays numerical analysis is the most effective cost-reducing alternative to experimental tests and it enables structure examination by means of a computer.

    Opis:
    The paper compares numerically modeled crack propagation in a steel specimen with a real process of fiber separation. The objective of the study was to perform numerical analysis of crack propagation in order to determine the shape of a crack and the distribution of stresses in the entire model. A CAD model of the test specimen was prepared based on geometric parameters determined for a real model. The numerical analysis was performed using the computer simulation program Abaqus 6.14. The experiment of specimen bending was conducted using bench tools. Crack propagation was simulated by the numerical method xFEM which enabled visualization of fiber separation in the test specimen. The numerical results of crack propagation were compared with the experimental findings about cracking in a real specimen.

    Opis:
    Nowadays numerical methods are a powerful tool to simulate real processes. Polymer materials are increasingly used in engineering solutions. ABS is a common material used interchangeably with respect to traditional materials. Process for the production of components for rese-arch on 3D printers is becoming more widespread and accessible to ordi-nary users. Crack propagation process was carried out at the same time to compare results through experiments performed on the testing machine and numerical study. Cracking process was carried out by finite element method, implemented on the basis of simulations xFEM. This method allows to conduct research related to the separation of the material nodes, in places of highest stress levels that exceed the limits of plasticity and strength of the material. The analysis involved comparison of the shape of the resulting cracks through experimental and numerical way.

    Opis:
    The paper describes the process of symmetric bending of an aluminium specimen using two independent environments for numerical analysis. A FEM analysis is performed on an aluminium channel section. A comparison is made between the bending process performed in the Abaqus environment and that run with the Deform-3D system. In both numerical analysis systems, the crucial point is to determine the state of reduced stresses for a designed computer model. The paper provides a visual comparison of the profiles subjected to bending; it also determines displacements and stresses in the tested structures. To perform a nonlinear static analysis, we define a material model, determine boundary conditions, interactions as well as generate a mesh. The results produced with the two numerical systems agree to a very high extent.

    Opis:
    The study involved performing a numerical thermal analysis of selected components in a car braking system. The primary goal of the study was to determine the regions which are most susceptible to variations in temperature, and to determine the degree of thermal impact upon them. The analysis was performed using the Abaqus environment. The examined components of the braking system were made of materials reflecting mechanical properties of the real subassemblies. The FEM analysis enabled determination of the distribution of temperature in the system with respect to the properties of the investigated materials and applied boundary conditions.

    Opis:
    This paper reports the results of a numerical analysis of buckling in a carbon-fibre reinforced plastic (CFRP). The analysis involved determination of the first buckling mode and critical forces for the tested composite. The composite was tested for six different ply orientations. The analysis was performed on a closed section composite column. The objective of the analysis was to determine critical forces affecting the composite profiles with the applied ply orientations and, thus,to determine the laminate ply orientations which can carry the heaviest loads. The numerical modelling and all computations were performed using the Abaqus 6.14 software. In the analysis, we took account of boundary conditions and performed a discretization process in order to obtain correct results.
