The ductility of a material describes the amount of deformation that precedes fracture.
EK431
The response of the beam remains linear and elastic almost to the stage when the stress in the extreme fibre has reached the value of the yield stress. From there […]
EK429
The plastic design method is based on the following assumptions: The material has the capacity to undergo considerable plastic deformation without danger of fracture. Ductility of steel (that is, a […]
EK240
The concrete specimen under axial compression may fail in the separation into columnar pieces by what is known as splitting, or columnar fracture. This failure occurs when the strength of […]
EK135
More serious are cracks which propagate at high speed in a brittle (or unstable) fashion, for which some of the internal elastic strain energy stored in steel is released and […]
EK130
Structural steel may fracture at low average tensile stresses after a large number of cycles of fluctuating load. This high-cycle fatigue failure is initiated by local damage caused by the […]
EK129
The steel remains elastic while in linear range, and recovers perfectly on unloading. The limit of the linear elastic behaviour is often closely approximated by the yield stress. Beyond this […]
EK94
There are two main assumptions for first order plastic analysis: The structure is made of ductile material that can undergo large deformations beyond the elastic limit without fracture or buckling. […]
