Influence of anisotropy on creep in functionally graded variable thickness rotating disc

The study is carried out to develop a mathematical model to analyze creep response of a varying thickness rotating disc made of anisotropic functionally graded 6061Al-SiC w .composite. The thickness and content of reinforcement (SiC w ) in the disc are assumed to decrease radially according to power law. The yielding of disc material is according to Hill’s criterion and creeping as per threshold stress based law. The developed model is used to...
