Abstract

Neutral area of intensity of stress at banding layer composite materials is area on which intensity of stress equals zero. Radial stress at whole section has negative value and maximal intensity on neutral area of stress, and tangential change value from negative to positive or other way around. Neutral area of deformations is area on which fibers are not deformed, and their size before deformation stays the same after deformation. Position of neutral axis at banding two layer composite materials depends on: mechanical characteristics of layer materials, radius of banding, thickness of layers, area of temperature of deformation, speed of deformation and deformation, history of deformation, methods for making two layer composite materials, position of layers in relation to radius of banding or profiling etc. Their positions can successfully be determined by experimentally-analytical methods, on condition that we have modern equipment for preparation, execution and analysis of results of experimentally-analytical researches.
