ABSTRACT

This paper presents an inverse modelling that is used in conjunction with the FEM and representative joint test results to develop a numerical model usable for optimisation of a prototype timber fastener with projections on both sides, i.e. a double-sided steel nail plate. Although inverse modelling as an approach is well established in other scientific and technological fields that employ numerical modelling, it has not been explicitly applied to the punched steel plate joint problem. The main advantage of the approach presented in this paper is that the formulation allows for simple material constitutive laws and geometric models. There is no general loss of accuracy in the model prediction capabilities of the key joint performance measures. Complex interaction criteria such as contact at the tooth-wood interfaces also become manageably incorporated into the model as a result of the simplifications.
