Residual stresses in bonded armor tiles for in-vessel fusion components
The residual stresses in a bonded tile/substrate structure were analyzed using both analytical and finite element methods.
Beam theory and 2-D elasticity solutions were compared and the latter was found to be more accurate, due to inadequate boundary conditions used in beam theories. Agreement between variational elasticity and finite element solutions was favorable, but the increased flexibility of finite element codes makes them superior when non-linear problems are considered.
The response of the calculated stress states to changes in various model dimensions and material parameters was studied parametrically. In general, dimensional changes were found to be significant only for short, thin tiles.
