Intro to Large Deformation — Lesson 1

Deformations are inevitable.  Even the smallest load on a very hard body can cause some deformation.  Depending on the object and the amount of load, these deformations may be too small or too large. In fact, this is how the stresses are developed inside the bodies.

But when an object undergoes deformation that is large enough to change its shape/size, it triggers other changes that can impact a system's response.

Examples include a fishing pole,

a rotating part in the car engine,

or even a wind turbine.

It's important to know what physical changes are triggered by large deformations in order to understand their importance in an application. In this lesson, we will spend some time familiarizing ourselves with these changes and learn in detail how they modify a system's response.
