Experimental & Computational Mechanics Lab
Additive manufacturing
Additive manufacturing (AM), often referred to as 3D printing has revolutionized the engineering of parts and structures with complex inner architectures. Unlike traditional manufacturing methods, which typically involve subtracting material from a solid block, additive manufacturing builds objects from the ground up, based on a digital model. The group works on polymer, carbon fiber reinforced and metal AM single step and hybrid methods.
Advanced Materials
Architectured materials can be coined to exhibit properties that well differ from the ones typically encountered in common engineering materials. Lightweight designs based on strut, triply periodic minimal surface (TPMS) and stochastic, spinodal designs are characteristic examples of the kind. Metamaterials with tailored static, wave propagation, and dynamic transmissibility are developed.
Architected Metastructures
The advancements in addtive manumacturing and materaterial design have paved the development of a novel class of structures that exceed the bounds of solid designs. Metastructures allow for extraordinary attributes out their tailored inner microstructure. The group investigates extraordinary static and dynamic performance characteristics exploiting diverse metamaterial topologies and base materials.
Machine Learning & Explainability
Machine Learning has become a powerful tool in materials science, enabling significant advancements in material discovery, design, and performance prediction. It allows for the prediction of effective properties, the association of processes and effective behaviors, as well as the inverse design of advanced materials. Moreover, it provides the basis for a series of Explainability analysis tasks to be performed, assessing feature importances, interactions and dependencies.
