Abstract: A method of generating force between a structure and an additional member, particularly for reinforcing an existing structure so that an additional member can share existing load. Pre-cooled or pre-heated shims of shape memory alloy (SMA) are inserted between the additional member and the existing structure, or between different sub-units of the additional member, or between the additional member and shoes fixed for this purpose to the existing structure. On subsequent warming or cooling the SMA shims expand to apply compressive forces to the portions of the structure, additional member or shoe(s) with which they are in contact on their opposite sides. Further compressive, tensile, flexural or torsional forces will be developed within other parts of the structure and additional member as a result of the shim expansion depending on the particular arrangement.

Abstract: A cylinder block production method is characterized by having, as a step prior to a cast-enclosing step of cast-enclosing a cast iron-made cylinder liner within a cylinder block body, an erosion-wash step of washing an outer peripheral wall surface of the cylinder liner and eroding a portion of a base structure of the cast iron forming the outer peripheral wall surface of the cylinder liner so as to form many small protrusions on the outer peripheral wall surface by jetting a high-pressure fluid onto the outer peripheral wall surface of the cylinder liner, in order to improve strength of adhesion between the cylinder liner and the cylinder block body. Since the base structure is partially eroded, complicated-shape small protrusions can be formed. Furthermore, sand and a mold release agent adhering to the outer peripheral wall surface of the cylinder liner can be removed. Therefore, the adhesion strength will improve.
