DETAILS

product description:
Thickness of 4.5mm to 25mm steel, known as the plate. Thickness of 25.0-100.0mm called thick plate, the thickness of more than 100.0mm for the extra thick plate
Product Usage:
Plate is mainly used in construction, machinery manufacturing, container manufacturing, shipbuilding, bridge construction. Can also be used to manufacture all kinds of containers, furnace shell, furnace plate, bridge and automobile static steel plate, low alloy steel plate, shipbuilding steel plate, boiler steel plate, pressure vessel plate, tread plate, automobile girder plate, tractor parts and welding Components and so on.
 
Although the thickness is small, the deformation and bending deformation caused by transverse shear are of the same order of magnitude. When analyzing the stress and deformation under static load, the transverse shear effect must still be considered. The normal stress perpendicular to the surface of the plate is negligible . In analyzing the stress and deformation under dynamic load, in addition to considering the transverse shear effect, the inertia force and damping moment of the micro-section must also be considered. Plate in the machinery industry has long been widely used. Although the thickness is small, the deformation and bending deformation caused by transverse shear are of the same order of magnitude.
