Pozycja Analytical and Experimental Determination of FML Stiffness and Strength Properties(Wydawnictwo Politechniki Łódzkiej ; Katedra Dynamiki Maszyn - Wydział Mechaniczny Politechniki Łódzkiej, 2015) Kamocka, Monika; Mania, Radosław J.The paper presents application of analytical methods of determining the mechanical properties of Fibre Metal Laminates. Chosen micromechanical methods were employed to predict elastic moduli and strength of FML panels. Prediction was conducted on two levels i.e. micromechanics where properties of a single composite lamina (prepreg) were analyzed, and macro-mechanics to determine properties of a full FML hybrid material. The properties of a single GFR lamina were predicted by Rule of Mixture Method (ROM), inverse Rule of Mixture Method with correction factor, Halpin Tsai Method, Tsai Method and Wilczynski Method application. Properties of full 3-2 FML lay-up were determined using the Rule of Mixtures. Analytical results were verified by experimental tests. Tensile and bending test were performed on rectangular standard coupons of 3-2 FMLs.Pozycja Mechanical Properties of the Mineral Cast Material at the Macro and Micro Level.(Lodz University of Technology. Faculty of Mechanical Engineering. Department Division of Dynamics., 2016) Kępczak, Norbert; Pawłowski, Witold; Klich, Marek; Kaczmarek, ŁukaszThe paper presents the results of experimental examination of the mechanical properties at micro and macro scale of the mineral cast composites. Studies have been conducted to verify the literature data about the value of tensile strength, compressive strength and Young’s modulus. Additionally as a part of this research Poisson’s ratio was determined, which has not been encountered in the current literature as deeply as in this work. In the next step, a scanning electron microscopy (SEM) studies have been carried out to analyze fractures of the samples after tensile and compression tests. These results were correlated with mechanical properties such as tensile strength and compressive strength, respectively. During fracture investigations, the contact interface between concrete filler and polymer was studied. As a result of this research the mechanism of deformation was formulated.Pozycja Analytical and Experimental Determination of FML Stiffness and Strength Properties.(Lodz University of Technology.

The examinations are performed within the frames of a project aiming at the elaboration of an experimental and industrial technology of producing constructively complex elements of machines and devices made of magnesium alloys with the method of investment casting. It has been proven that small numbers of Cr and V alloy additions improve the strength properties: Rm, A%, and the hardness HB of the obtained casts. The experimental casts were made in ceramic molds.
