 Stress analysis is the core goal of Scan&Solve and begins with a simple observation: when a force is applied to a material, it will deform.  In the following Scan&Solve simulation, a marble dome is shown deforming under the force of gravity  (note the deformations are magnified extensively to make them visible). Stress analysis is the core goal of Scan&Solve and begins with a simple observation: when a force is applied to a material, it will deform.  In the following Scan&Solve simulation, a marble dome is shown deforming under the force of gravity  (note the deformations are magnified extensively to make them visible).

 Another type of stress is **shear stress**.  While normal stress describes how parts of an object are pushed or pulled together, shear stress can be imagined as causing parts of an object to slide across one another.  In the following example, two blocks are sliding across each other.  Thus, there is a shear stress present between them. Another type of stress is **shear stress**.  While normal stress describes how parts of an object are pushed or pulled together, shear stress can be imagined as causing parts of an object to slide across one another.  In the following example, two blocks are sliding across each other.  Thus, there is a shear stress present between them.

 **Shear strain** is related to the angle of deformation of the object. The following image shows a cube under shear stress, which acts parallel to the cube faces as shown.  The shear strain can be observed, as the cube appears as if it has been squished into a parallelogram.  The colors show that a constant shear stress is present throughout the cube. **Shear strain** is related to the angle of deformation of the object.
