Medium and heavy plates are mainly used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction, etc. It can also be used to manufacture various containers, furnace shells, furnace plates, bridges and automobile static steel plates, low-alloy steel plates, shipbuilding plates, boiler plates, pressure vessel plates, checker plates, automobile beam plates, certain parts of tractors and welding. components, etc. Use of medium and heavy plate: widely used to manufacture various containers, furnace shells, furnace plates, bridges and automobile static steel plates, low alloy steel plates, bridge steel plates, general steel plates, boiler steel plates, pressure vessel steel plates, patterned steel plates, Specific applications of automobile frame steel plates, certain parts of tractors and welded components.
Although the thickness is small, the deformation caused by the transverse shear force and the bending deformation are of the same order. When analyzing the stress and deformation under static load, the transverse shear effect must still be considered, and the normal stress perpendicular to the plate surface can be ignored. . When analyzing the stress and deformation under dynamic load, in addition to the transverse shear effect, the inertial force and damping moment of the micro-segment must also be considered. Medium and heavy plates have long been widely used in the machinery industry. In recent years, due to the environmental requirements of high pressure, high temperature and strong radiation, the thickness of the plate in the project has increased, and many plates have been analyzed by the medium and thick plate theory.
