This paper aims at analyzing the interface strain using finite element method between bone and muscle in the human buttock. Research focuses on how fibril tissue damage might cause pressure ulcers and how different loading condition affects the interface strain between bone and muscle. The damaged interface was then modeled as interface crack. A manual mesh was created for this research in order to get more accurate result at the interface. Furthermore, the interface strain/stress was calculated in the local coordinate system of a normal and tangential direction along the curved interface. It was found that the changes in loading direction gave effects on strain at the tip of the breakage.
