Abstract: The stress of alloy layer and the displacement of the loaded point on metallicmultilayer materials bearing shoes on which tesling load is exerted have been researched. The computing formulas of the stress and displacement of the combined curved beam areestablished.Compared with finite element method and electrometric method,the results ofthe above caloulation seem to have good effect,from this,these formulas are proved to meetthe precision preseribed completely.
