Modelling of Low-velocity Impacts on Composite Beams in Large Displacement

Mattia Utzeri, Marco Sasso, Gianluca Chiappini, Stefano Lenci

The paper provides an evaluation of the nonlinear dynamic response of a cantilever beam made of composite material subjected to low-velocity impacts. The structure is assumed to respond in a quasi-static manner and modelled by a continuous…

Structural model updating based on metamodel using modal frequencies

Jutao Wang, Zhenzhong Liu, Liju Xue

Modal frequencies are often used in structural model updating based on the finite element model, and metamodel technique is often applied to the corresponding optimization process. In this work, the Kriging model is used as the metamodel.…
