Comprehensive Numerical Modeling of Prestressed Girder Bridges under Low-Velocity Impact

open access: yesBuildings
Accidental collisions involving over-height trucks that exceed vertical clearance limits and bridge superstructures frequently happen, resulting in compromised girders and potential threats to structural safety and performance.

Modelling of ductile failure in metal forming [PDF]

open access: yes, 2009
Damage and fracture are important criteria in the design of products and processes. Damage models can be used to predict ductile failure in metal forming processes. Nonlocal models avoid the mesh dependency problems of local damage models.
