In such case, it is typical for a contact of masonry units in the bed joint to locally develop stress concentration due to roughness of the surface.
Pointing is the outer face of the mortar bed joint and it is this bed that spreads the loads imposed on wall across the bricks or stones.
The main dilatancy characteristics are captured well including the dependence on the confining pressure and the uplift during the shearing which increases exponentially and is arrested at large shear deformation, indicating a smoothening effect on the bed joint.
The decisive finding is the interaction of the bridge vault with the breast walls--a critical point being the bed joint between the vault and the breast wall.
Eighteen-year-old Rory McIlroy, from Holywood in Northern Ireland, has never even played a major before, but with a 68 he went to bed joint third with current US Open champion Angel Cabrera, former US Open champion Michael Campbell, American Tour winner Boo Weekley and European Tour winner Markus Brier, of Austria.
Facing breast walls are locally degraded by cracks running along the heel bed joint between the arch and the wall, and by cracks in the bed joint at a level of the mortar bed and the protective concrete layer below the granite paving (in arch XIII a horizontal shift in the joint is evident as well, while in the area of degraded bed joints deposits of washed out salts can be seen, Fig 14).
2) Coping Stones: Depending upon the type of coping stones you should look for various things: On all copings the cross and bed joints should be sealed; the bed joints with cement and the cross joints with cement and an expandable type of caulking -- in order to prevent water penetration as the joints expand and contract with the weather.
Corroded nails are also a worry, as are cracked or eroded mortar bed joints on the ridge or hip ridge tiles.
In a Wrightian manner, the horizontality of the lawn and the density and compression of the garden wall are reinforced by the elongated proportion of Norman bricks with deeply raked bed joints and by the long shadows cast by projecting metal heads and stone sills of windows.
Check for signs of loose or slipped tiles and slates, corroded nails and cracked or eroded mortar bed joints on the ridge or hip ridge tiles.
On all copings, the cross and bed joints should be sealed; the bed joints with cement and the cross joints with cement and an expandable type of caulking, in order to prevent water penetration as the joints expand and contract with the weather.
