## Saving Time and Money Right Out of the Box with SOLIDWORKS

Read how Machitech customers literally become partners in “the Machitech experience” where they play an integral role in the product development process, thanks to SOLIDWORKS.

## Assuming Linearity: Linear Static vs. Nonlinear

Background
SolidWorks has several different tools available for analyzing structures. Static analysis (discussed in my previous blog article) is available with the purchase of SolidWorks Simulation (included in SolidWorks Premium). Nonlinear analysis is available with the purchase of SolidWorks Simulation Premium (see Figure 1).

Figure 1 – SolidWorks Simulation study types

When a force is applied to a structure (a pencil, a building, a fixture, etc.) the internal pressure in the structure builds up. We call this internal pressure, stress. As stresses rise, the structure gets longer or shorter. We call this elongation, strain. When we run a Static analysis, we are assuming that the relationship between stress and strain is a simple one; we assume the relationship is linear. By making this assumption, we can potentially make an otherwise difficult or sometimes impossible problem very easy to solve.

However, this assumption isn’t all true. In reality, the relationship between stress and strain is never “perfectly” linear. But this assumption is close enough for many scenarios, and the amount of error it introduces may be negligible.

## Visiting the Mariana Trench? SolidWorks knows if your sub can stand the pressure.

If you believe the people who manage the Wikipedia entry, the Mariana Trench in the south Pacific ocean is around seven miles deep. That's roughly the distance from here to my house. At that depth, the water pressure is so
