Some key concepts in the theory of elasticity and plasticity include: A plastic material (like clay or soft lead)
The interplay between these two theories allows scientists to predict the of materials. A perfectly elastic material would be brittle (like glass), snapping instantly when its limit is reached. A plastic material (like clay or soft lead) flows under pressure. Most engineering materials, such as steel, exhibit both: they are elastic under light loads and plastic under heavy loads. Conclusion
At its core, this field studies how materials deform under loads.
