Selecting "Shell" enables all probable types of stresses to appear, contrary to "Plate" in which only (out-of-plane stresses) appear like shear and moment, or "Membrane" in which only (In-plane-stresses) appear like tension and compression. In this video we are interested in all types of stresses so I selected "Shell". Selecting "Thick" allows deflections to be calculated based on moment and shear together, i.e. it does not neglect shear deformations, and this is the case in reality which means it gives me the most accurate deflections. "Thin" means calculating deflections based on moments only, it therefore saves running time when your structure is large. It gives accurate results when thickness is small compared to other dimensions. In my video I selected "Thick" because my structure is not that large, and so as not to spend much time comparing thickness with other dimensions. Sorry for not typing in Arabic because text goes messy when I use a mix of Arabic and English..
فضلا
ممكن معادلات التصميم شرح بالارقام خاصة CHECK SHEAR
جزاك الله خير يا هندسة لكن عندي سؤال
ليش تختار نوع shell ) shell thic)?

kindly explain more about shear check ?
ممكن الملف

i want the conversation in english
fantastic
Thanks a lot
