What is Tensile Strength? Tensile Strength of Steel and Other Materials
Tensile strength is the maximum stress up to which a material can be loaded without failure. When the tensile strength is exceeded, the material breaks or fails. This is also known as ultimate...
What is a Thrust Block? It’s Design, Construction, Types, Working, Differences with Anchor Block
A thrust block is a concrete pipe restraint that prevents the mainline from moving by transferring pipe loads (mainly due to pressure thrust) to a wider load-bearing surface. Usually, thrust blocks...
Brittle Fracture and Ductile Fracture: Definition, Mechanism, Differences
A fracture can be defined as the separation of the material into two or more parts. Failure of material can involve any of the two mechanisms; ductile fracture or brittle fracture. Both these...
AutoPIPE vs CAESAR II: Differences between CAESAR II & AUTOPIPE
What is Autopipe? Autopipe is a computer-based engineering program to determine pipe stresses, pipe support design, flange analysis, and equipment nozzle load analysis under dynamic and static...
Maximum shear stress theory provides failure criteria for mechanical components made of ductile material. This failure criterion is developed by the French mechanical engineer, Henri Tresca, and...
