中厚板批发是工程中常用的一类厚度远小于平面尺寸的板件。厚度4.5mm至25mm的钢板。厚度25.0-100.0mm的称为厚板，厚度超过100.0mm的为特厚板。
Medium and heavy plate wholesale is a common kind of plate which is much smaller than plane size in engineering. Steel plate with thickness of 4.5mm to 25mm. The thickness of 25.0-100.0mm is called thick plate, and the thickness is more than 100.0mm is the special thick plate.
厚度虽小，但横向剪力所引起的变形和弯曲变形属同一量级，在分析静载荷下的应力和变形时，仍须考虑横向剪切效应，垂直于板面方向的正应力则可忽略。在分析动载荷下的应力和变形时，除考虑横向剪切效应外，还须考虑微段的惯性力和阻尼力矩。中厚板在机械工业中早已有广泛应用。
The thickness is small, but caused by transverse shear deformation and bending deformation is the same order of magnitude, in the analysis under static load stress and deformation, considered the effect of transverse shear, perpendicular to the direction of the surface normal stress can be ignored. Besides the transverse shear effect, the inertia force and damping moment of the micro segment must be considered when analyzing the stress and deformation under dynamic load. Medium plate has already been widely used in machinery industry.

近年来由于高压、高温和强辐射的环境要求，工程中板的厚度有所增加，很多板件均改用中厚板理论进行分析。中厚板主要应用于建筑工程、机械制造、容器制造、造船、桥梁建造等。还可以用来制造各种容器、炉壳、炉板、桥梁及汽车静钢钢板、低合金钢钢板、造船钢板、锅炉钢板、压力容器钢板、花纹钢板、汽车大梁钢板、拖拉机某些零件及焊接构件等。
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 plate parts are analyzed by the theory of plate. Medium plate is mainly used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and so on. Can also be used to manufacture all kinds of containers, furnace shell and plate, bridge and vehicle static steel, low alloy steel plate, ship plate, boiler plate, pressure vessel steel plate, embossed steel plate, steel plate for automobile frames, tractor parts and some welding components etc..
