The effect of reinforcement structure and profile shape of curved composite disks on their limiting rotational speed
Source abstract
Abstract
A problem for determination of an upper kinematic limit of load-carrying ability of complex-reinforced flat and curved rotary disks of constant and variable thickness has been stated and solved by the linear-programming technique. Disks with meridional-circumferential fiber arrangement are shown to have the highest limiting angular velocity. Curvature of a disk impairs drastically its load-carrying ability; the maximum safe rotational speeds of disks operating within the elastic deformation of the composite material phases are several-fold lower than the ultimate permissible speeds.
