Design Principles
"Computational modeling can accurately predict the performance of novel material systems, reducing the need for extensive physical testing and accelerating design iteration."
This capability allows designers and engineers to virtually test and optimize structural designs using novel materials like rubberized concrete before physical prototyping. It accelerates the development cycle and reduces material waste by identifying optimal configurations and material properties through simulation.
What This Means for Your Design
Computer simulations (FEA) can accurately show how new types of bricks, made with recycled rubber, will behave when used in walls, saving time and resources compared to building many real walls to test.
