The Effect of Stress Redistribution in a Thick-Walled Sphere Made of Shape Memory Alloy at Direct Phase Transformation under Constant Pressure
Year: 2024
Type: article
Abstract: The coupled problems of changing the stress-strain and phase state in a thick-walled spherical shell made of a shape memory alloy, the material of which undergoes a direct thermoelastic phase transformation associated with a decrease in temperature uniformly distributed over the entire volume of the material under the action of constant internal or external pressure, are solved. The effects of significant overstressing of the body layers adjacent to the inner boundary and significant unloading of the layers adjacent to the outer boundary associated with the movement of the phase transition completion front through the material were found.
