Design Principles

"Material behavior during manufacturing is not always scale-independent; incorporate gradient effects into simulations for greater fidelity."

Accurate simulations are crucial for industries like aerospace and automotive, where performance predictability is paramount. By moving beyond classical models, designers and engineers can better anticipate material responses during manufacturing, reducing costly errors and improving final product quality.

What This Means for Your Design

Sometimes, how a material behaves depends on how small the piece is or how quickly it's being shaped. Old simulation methods don't always see this, but newer 'strain gradient plasticity' methods do, making them better for predicting how things will turn out when you make them.
