Damage factor assessment in plate structures using finite element method

Abstract EN

Using finite element analysis, damage factor (DF) for damaged plate structure is presented.

The damage factor (DF) is able to localize the damage severity in the plate by a clear “jump” at the location of the damage in plate.

The magnitude of the damage factor (DF) presented here varies linearly with the exact damage measure (DM) imposed in the plate.

A new intuitive mode dependent factor is introduced.

The mode dependent factor α is to improve the damage factor (DF) to be able to quantify the severity of the damage in plate.
