A Study on the Facture Behavior of Laminated Steel Composites at Low Temperature

Laminated steel composites are made from spring steel and mild steel by rolling process. Experiments for impact test are carried out and the fracture behavior of laminated steel composites are compared with that of homogeneous steel. Also, fracture models of laminate composites are analyzedby finite element method and the computed fracture stress is compared with experimental results.
