However, the designer reduces the structural cost without taking into account uncertainties concerning material properties, geometric dimension and loading.
Suitable geometry, material properties and loads are assumed, and an analysis is then performed to provide a detailed behavior of the structure.
Over the last ten years there has been an increasing trend in analyzing structures using probability information on loads, geometry, material properties, and boundary conditions.
In the structural analysis of engineering design, there exist uncertainties in loading, material properties, geometry, and environmental conditions.

It can be indicated that some materials which can react with NaOH go into the aqueous phase after the reaction of NaOH solution with Daqing crude oil for a short time (1d), so that the interfacial active substances contained in the oil phase are less then that in Daqing model crude oil leading to the increase of interfacial tension.

These techniques permit to avoid locking problems even in very bad conditions (nearly incompressible materials, very thin elements conducting to large aspect ratios, distorted element geometry…).
It is indeed expected that a high gradient of stress and strain along the thickness direction is present during the deformation of thin materials (during e.g. a bending deformation mode).
Thanks to the symmetry of the process (the geometry of the sheet, the material properties and the loading), only a quarter of the sheet was meshed and adequate boundary conditions were imposed.
