2. Spackling paste - Wikipedia

   en.wikipedia.org/wiki/Spackling_paste

   Spackling paste or spackle is a putty used to fill holes, small cracks, and other minor surface defects in wood, drywall, and plaster. [1] [2] Typically, spackling is composed of gypsum plaster from hydrated calcium sulfate and glue.

3. Stress corrosion cracking - Wikipedia

   en.wikipedia.org/wiki/Stress_corrosion_cracking

   mild steel cracks in the presence of alkali (e.g. boiler cracking and caustic stress corrosion cracking) and nitrates; copper alloys crack in ammoniacal solutions ( season cracking ); high-tensile steels have been known to crack in an unexpectedly brittle manner in a whole variety of aqueous environments, especially when chlorides are present.

   Home repair involves the diagnosis and resolution of problems in a home, and is related to home maintenance to avoid such problems. Many types of repairs are " do it yourself " (DIY) projects, while others may be so complicated, time-consuming or risky as to require the assistance of a qualified handyperson , property manager , contractor ...

6. Glaze defects - Wikipedia

   en.wikipedia.org/wiki/Glaze_defects

   Crazing is a spider web pattern of cracks penetrating the glaze. It is caused by tensile stresses greater than the glaze is able to withstand. [1] [2] Common reasons for such stresses are: a mismatch between the thermal expansions of glaze and body; from moisture expansion of the body; and in the case of glazed tiles fixed to a wall, movement of the wall or of the bonding material used to fix ...

7. Fracture mechanics - Wikipedia

   en.wikipedia.org/wiki/Fracture_mechanics

   Fix the boundary so that the applied load does no work and then introduce a crack into the specimen. The crack relaxes the stress and hence reduces the elastic energy near the crack faces. On the other hand, the crack increases the total surface energy of the specimen.
