Examples of this class include many of the rare or precious metals, strip or extruded shapes in base metals or alloys, some bearing metals, some hard or soft magnetic materials, etc.
Prandtl-Vesic of ultimate bearing capacity of strip foundation belongs to the plane strain problems, which adopt step superposition method to obtain the formula of ultimate bearing capacity.
