The static strain at the fillet of cylinder block was evaluated by the finite element method based on a single model of a cylinder block. The fillet is stress concentration part of a cylinder block that is used internal combustion engine. The strain along the fillet varied depending on the position, which was mainly attributed to the stiffness of the cylinder block and the location of cylinder head bolts. An appropriate range of the tightening force of cylinder head bolts for fixing was also evaluated. The minimum force was determined from the minimum pressure on the head packing not to leak the combustion gas. The maximum force was determined from the maximum static strain at the fillet of cylinder block above which cracks could be initiated. This method can be used for optimum designing of cylinder block.
