There are several different kinds of geometric non-linearities that can occur in a CAE (Computer-Aided Engineering) project. These non-linearities arise when the behavior of the structure being analyzed deviates from linear assumptions.

1. Large Deformation: This non-linearity occurs when the structure undergoes significant deformations. In linear analysis, small deformations are assumed, but in reality, large deformations can occur. This can lead to changes in the geometry and stiffness of the structure.

2. Contact Non-linearity: Contact non-linearity arises when there is contact or interaction between different parts of the structure. This can occur in situations where there are sliding or sticking interfaces, or when there is a need to model the interaction between two or more components.

3. Material Non-linearity: Material non-linearity refers to the behavior of the material being analyzed. In linear analysis, materials are assumed to have constant properties, but in reality, many materials exhibit non-linear behavior. This can include plasticity, viscoelasticity, or hyperelasticity, where the material response changes with stress or strain.

4. Buckling: Buckling is a form of geometric non-linearity that occurs when a slender structure, such as a column or beam, undergoes instability and collapses under compressive loads. Buckling analysis is important to determine the critical load at which buckling occurs.

To better understand these geometric non-linearities, let's take a look at some figures:

These figures illustrate the different types of geometric non-linearities that can occur in a CAE project. It is important to consider these non-linearities to accurately model and analyze the behavior of the structure under various loading conditions.
