Numerical modelling of forces, stresses and breakages of concrete armour units

Numerical modelling has the potential to probe the complexity of the interacting physics of rubble mound armour systems. Through forward modelling of armour unit packs, stochastic variables such as unit displacement and maximum contact force per unit during an external oscillatory disturbance can be predicted. The combined finite-discrete...

Rock Armouring to unconventional breakwaters: The design implications for rock durability

This paper identifies the need for quantitative durability testing of rock for use on dynamically stable rock armoured slopes. The derivation and use of a suite of engineering tests for rock quality is considered, and the limitations of Simple accept/reject criteria discussed. Recent developments in techniques for the quantification of armour...

The influence of armourstone shape and rounding on the stability of breakwater armour layers

This is the second of two reports relating to a collaborative prograrmne of random wave flume tests to quantify the effect of rock shape on stability. The first report, SR 150, by Hydraulics Research, Wallingford, gives a summary of recent advances in design methods for rock armoured coastal structures and presents a detailed description of the...
