| Abstract [eng] |
The theme of Master project of Mechanical engineer is actual nowadays, becauce multilayer structures (MS) are replacing many of the traditional one-material structures. MS has many unique features, like greater resistance to deformation and qualitatively new physical or chemical characteristics. Materials, their alignment and geometry of the selection options in MS are abundant. It is cheaper, we can reduce the weight and the rigidity make similarly. This work examines multilayer structures (MS) cross-section of the karnel, its formations and its evalution from the cross-section area, cross-sectional shape and the elastic modulus. Homogeneous core of the cross-sectional is compared to the multi-core cross-section of the rod. Seeking for cross-section tension with the same mark, the engineer must ensure, that the cross-section should not cross neutral line, and this can be done by adding a bar functional force to the known as the cross-section of the karnel. Research result is obtained that the cross-section of the core increases with increasing cross-sectional area, and vary respectively to the changing shape of the block. Reducing the material elastic modulus, the karnel of cross-section is increasing. |
