Abstract

Abstract

En 中文
• Flexels are energy-based elements featuring multivalued force–displacement curves. • The flexel formulation yields an ecosystem of elements to build reduced order models. • Flexels can represent nonlinear springs, flexures, cables, fluids or contact. • The arclength method enables nonlinear static simulations of flexel assemblies. • The framework is implemented in an open-source Python library.
