The conference series provide a forum for academic and industrial researchers, scientists, and engineers to meet to discuss recent developments in aluminum science, technology, and applications.
The ICAA conferences cover all aspects of aluminium alloy technology, and in ICAA15 particular emphasis is placed on nine topics, including  Casting and solidification;  Phase transformations;  Thermo-mechanical processing;  Metal plasticity and forming;  Strength, fracture and fatigue;  Advanced atomic-scale characterization;  Corrosion and surface properties;  Novel processes and alloy design;  Modelling and simulation.

LS-DYNA, a versatile finite element analysis (FEA), incorporates advanced material models and numerical methods to simulate such complex phenomena.
