Abstract

This paper is a review of activities concerning various damage tolerance modelling and testing aspects of sandwich panels for typical Naval applications. It starts with a review of testing methods for primarily core materials and how to extract properties and data required for damage tolerance assessment. Next some typical damage types are defined and how they are modelled with the aim of predicting their effect on load bearing capacity. The paper then describes in brief how such models can used in the context of providing a systematic damage assessment scheme for composite sandwich ship structures.

Notes

Acknowledgment

The work summarised in this chapter has been ongoing since the 1980s with various support. Thanks are due to The Swedish Defence Materiel Administration and Mr. Anders Lönnöfor funding parts of this. The Nordic Industrial Fund (NI) provided support for a long time in the 1990s. A lot of the more recent work was performed within the WEAG-project saNDI in collaboration with Prof. Brian Hayman at DNV. During most of the past 10 years invaluable support has been provided from the Structural Mechanics Programme of ONR through programme officer Dr. Y. Rajapakse.
