چکیده مقاله:

A hand cane is one of the most widely used medical devices, especially for disabled and elderly people. Thecurrently available hand canes in the market are generally made of wood or light metals, but due to the importance ofweight and dimensions, a competitive product can be proposed which uses composite. In this paper, an analytical methodis used to calculate stresses through the wall thickness of a multi-layered composite cylinder made of orthotropic materialto present a proposal for a composite hand cane. This method permits accurate stress analysis of thick-walled compositecylinders subjected to axial load, torsional load, and bending moment. Also, a numerical model is simulated for acomposite cylinder subjected to bending moment with a compression axial load. Different stacking sequences anddiameters were considered and the stresses of each case were calculated. Finally, the failure criteria are used to evaluatethe optimum case.
