Henan malpractice Construction Engineering Testing Co., Ltd. is a professional testing company, is one of the qualification place in Henan Province since the first detection through examination of business. Business in the Pile qualification qualification, the qualification grade steel, a qualified indoor environment, building energy efficiency testing, subject testing, materials testing, curtain detection, detection of roads and bridges, air defense projects to detect a number of test qualification and testing laboratories. Material deformation under external force when the external force disappears, material deformation can disappear completely restored to its original shape and nature called elastic. This deformation is called a recoverable elastic deformation, the elastic deformation of the spring within its scope. Material produced under external force deformation, Ye pile testing agency, when the external force disappears, the material remains deformed shape and size, pile testing, and the nature of the material damage does not occur is called plasticity. Such external force disappears after irreversible deformation called plastic deformation.
