Abstract
Ring-shaped shape memory alloys put disk-shaped ceramic materials in a state of compression. The rings are radially deformed to introduce plastic strain into the rings. The rings are sized to closely receive the disk-shaped ceramic strike plates. When the assembly is heated, the rings attempt to regain their original shape and thereby put the ceramic strike plates into uniform, two-dimensional compression.
