W artykule opisano wyniki badań przeprowadzonych w aparacie trójosiowego ściskania na próbkach gruntów spoistych o nienaruszonej strukturze. Dla gruntów o szerokim zakresie zmienności wskaźnika plastyczności wykonano kilkadziesiąt oznaczeń parametrów wytrzymałościowych – kąta tarcia wewnętrznego ((φ) i spójności (c'), oraz wytrzymałości na ścinanie w warunkach bez odpływu (cu). Na podstawie analizy wyników badań w odniesieniu do dotychczas stosowanych norm i literatury przedstawiono zależność między wskaźnikiem plastyczności gruntów a kątem tarcia wewnętrznego. Zwrócono również uwagę na przyczyny zawyżania wartości spójności gruntów, przyjmowanej do obliczeń geotechnicznych. Przywołano kilka zaleceń normy Eurokod 7, dotyczących interpretacji wyników badań wytrzymałościowych.

Assessment of strength parameters of beech plywood in terms of failure criteria. The failure state in a composite layer being in the complex state of stress is defmed using the so-called material failure theories. They describe the yield surface of the material, for which the limit of linear elasticity is determined. Failure theories formulated for anisotropic materials are more complex. The paper presents the results of research on strength and deformation of the beech veneer during tension loading in relation to slope of grain. Results of the performed investigations were presented in the form of graphs end figures.

Numerical and analytical analysis of the stress-strain relations to extended beech plywood. The study presents a theoretical and numerical analysis of problems connected with the determination of strength parameters in multilayer beech plywood with varied layer configurations. Analytical calculations were performed in accordance with the classical theory of thin plates lamination in view of the theory of elasticity taking into consideration the Kirchhoff-Love hypothesis. The analyses focused on models of composite layers in plane stress. Values of components of transformed stiffness matrices were estimated theoretically together with those of flexibility in the axial and non-axial configurations of individual laminate layers. A verification was made of analytical calculation results with computer simulation results made on numerical models using the finite element method (FEM). Results of investigations are presented in the form of tables, graphs and graphic visualization of FEM calculations.

Strength properties of structurally reinforced plywood. The study determined the degree of improvement of mechanical properties of 19 layer beech plywood with a thickness of 10 mm by introducing two layers of structural reinforcement in the form of aramid, glass and carbon fabric. For manufactured plywood, density, static bending strength and modulus of elasticity in static bending, toughness strength and impact bending strength were examined. It was determined, that the use of carbon, aramid and glass fabrics bonded with epoxy glue for structural reinforcement of plywood, has positive effect on strength parameters. The best results of improvement to the strength parameters of plywood is achieved by inserting two layers of carbon fabric.

Current trends to improve the quality and reliability of manufactured finished products cause that more and more attention is paid to the optimisation of rigidity-strength dimensioning of furniture elements constructional nodes. The objective of this study was to estimate the effectiveness of static optimisation methods determining the minimum of material volume in time function and sampling number. Moreover, the performed investigations aimed at establishing minimal dimensions of component elements of the construction at maximum strength parameters. The experiments carried out revealed that static optimisation of the construction of the chair with the aid of the Monte-Carlo method integrated with the FEM environment allowed to reduce material consumption to 53% of the initial volume within 17 seconds of work of the application. A sub-optimal solution, sufficient for engineering practice, is reached, on average, in time 18 times shorter than that reached using the random walk method.
