Deformation and failure
WebAug 28, 2024 · The deformation behavior of the rocks in the strong toppling deformation zone is complex and can be summarized into three basic failure modes: intercalated shear sliding, discontinuous tensile fracture, and cut-bed tensile sliding (Figure 9). Intercalated shear sliding is a common phenomenon in schistosity planes and weak rock belts. WebAug 31, 2024 · Plastic deformation - This may be irreversible. Soft thermoplastics have a rather large plastic deformation variance, as do ductile metals such as copper, silver and gold. Metal fatigue - This occurs primarily in ductile metals. Metal fatigue has been a common cause for failure, especially before the process was well understood.
