Notice of Retraction The safety evaluation of a hook combining testing and simulation

The load capacity of a hook (latch) which is a component of lock mechanism plays a key role in the safety of locking. A practical method to assess the load acting on the hook is presented. Although the use of static load testing method could get some veritably results, it has a limitation that the data measured in the test could not fully reflect the hook's load capacity. Although the use of finite element simulation method is more convenient and comprehensive, the simulation results are often unreliable for many reasons. The proposed method combines the benefits of the load testing method and the simulation method, which is proved to be accurate and feasible. The safety evaluation of the hook can provide a useful reference for engineers to carry out safety evaluation for some engineered systems.
