中厚板批發(fā)是工程中常用的一類厚度遠(yuǎn)小于平面尺寸的板件。厚度4.5mm至25mm的鋼板。厚度25.0-100.0mm的稱為厚板，厚度超過100.0mm的為特厚板。
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.
厚度雖小，但橫向剪力所引起的變形和彎曲變形屬同一量級，在分析靜載荷下的應(yīng)力和變形時，仍須考慮橫向剪切效應(yīng)，垂直于板面方向的正應(yīng)力則可忽略。在分析動載荷下的應(yīng)力和變形時，除考慮橫向剪切效應(yīng)外，還須考慮微段的慣性力和阻尼力矩。中厚板在機(jī)械工業(yè)中早已有廣泛應(yīng)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.

近年來由于高壓、高溫和強(qiáng)輻射的環(huán)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論進(jìn)行分析。中厚板主要應(yīng)用于建筑工程、機(jī)械制造、容器制造、造船、橋梁建造等。還可以用來制造各種容器、爐殼、爐板、橋梁及汽車靜鋼鋼板、低合金鋼鋼板、造船鋼板、鍋爐鋼板、壓力容器鋼板、花紋鋼板、汽車大梁鋼板、拖拉機(jī)某些零件及焊接構(gòu)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..
中厚板用途：廣泛用來制造各種容器、爐殼、爐板、橋梁及汽車靜鋼鋼板、低合金鋼鋼板、橋梁用鋼板、造般鋼板、鍋爐鋼板、壓力容器鋼板、花紋鋼板、汽車大梁鋼板、拖拉機(jī)某些零件及焊接構(gòu)件具體應(yīng)用。
The plate uses: widely used in the manufacture of various containers, furnace shell and plate, bridge and vehicle static steel, low alloy steel plate, bridge plate, boiler plate, steel plate, a pressure vessel steel plate, embossed steel plate, steel plate for automobile frames, tractor parts and components of some specific applications.
