Accropode (1981) The Accropode is a single-layer artificial armour unit developed by Sogreah in 1981. Accropode concrete armour units are applied in a single layer. Ecopode (1996) The Ecopode armour unit with a rock-like appearance was developed by Sogreah to enhance the natural appearance of concrete armourings above low water level.
Ordinary concrete C25/30 is normally appropriate for the production of Xbloc armour units. However, often concrete of higher strength is applied for other reasons, e.g. early strength for faster de-moulding, ice loads, etc. By omitting reinforcement, time and costs are cut and the armour units are less vulnerable to long term corrosion damage.
Armor conditioning procedures are outlined in ASTM E3078 Standard Practice for Conditioning of Hard Armor Test Items. [10] Generally, textile armor material temporarily degrades when wet. [citation needed] As a result of this, the major test standards call for wet testing of textile armor. [12] Mechanisms for this loss of performance are not known.

Hudson's equation, also known as Hudson formula, is an equation used by coastal engineers to calculate the minimum size of riprap (armourstone) required to provide satisfactory stability characteristics for rubble structures such as breakwaters under attack from storm wave conditions.
This was due to issues with the armor quality of the prototypes. [14] The Japanese Ministry of Defense announced that further prototype testing would end in 2018, due to concerns of a lack of adequate bulletproofing material that can be used and whether revisions can be made to meet the target production and the costs in time. [15] [16]
Armourstone along the sea wall south of Dawlish Warren (UK) Armourstone is a generic term for broken stone with stone masses between 100 and 10,000 kilograms (220 and 22,050 lb) (very coarse aggregate) that is suitable for use in hydraulic engineering.
