Effect of the silicon-carbide micro- and nanoparticle size on the thermo-elastic and time-dependent creep response of a rotating Al–SiC composite cylinder
TL;DR: In this article, the history of stresses and creep strains of a rotating composite cylinder made of an aluminum matrix reinforced by silicon carbide particles is investigated, and the effect of uniformly distributed SiC micro-and nanoparticles on the initial thermo-elastic and time-dependent creep deformation is studied.
