文摘
- •
We propose a new challenging benchmark for nonlinear structural identification.
- •
The nonlinearity is either localized or distributed, depending on the applied load.
- •
Such behaviour is due to the buckling of an element connecting two offset beams.
- •
A finite element implementation of the benchmark is briefly described.
- •
A Matlab p-code of such implementation is made available to the interested reader.
