Experimental and numerical study of inelastic behavior based on simulated cylinder head specimen under thermal cycling conditions

Huabing Zhang et al.

Summary: This study developed a transient thermal cycle analysis method based on the viscoelastic plastic Chaboche model to quantitatively consider the local deformation and leakage failure of marine engine cylinder heads. Through verification and analysis of the specimens, it was found that the inelastic deformation induced by temperature cycling leads to gradual leakage failure in the cylinder head.
