Taking the allowable design stress for aluminium as 90 N/mm². The estimated plate thickness required at base of tank is 0.1612m.
Stress is a force per unit area that occurs in materials as a result of external forces, uneven heating, or permanent deformation. It is used in physical sciences and engineering to accurately describe and predict the behavior of elastic, plastic, and fluid materials. A stress is defined as the product of a force divided by an area.
There are numerous types of stress. Shear stress is caused by forces that are parallel to and lie in the plane of a cross-sectional area of the material, as opposed to normal stress, which is caused by forces that are perpendicular to the area.
