Domain-decomposed spectral-ritz framework for 3D elastic dynamics of polyhedral structures

Key Points

• Elastic dynamics is effectively modeled using a domain-decomposed spectral-Ritz framework, enhancing accuracy across polyhedral structures.
• The study shows notable efficiency gains, achieving a computation time reduction by approximately 30% in complex 3D geometries.
• Using spectral methods allows for precise simulations of elastic responses under various loading conditions, a significant advancement for engineering applications.
• This framework may enable better design strategies, but its application is currently limited to complex polyhedral geometries.
