3 cards from this section. Quick, good the night before a test.
What is tensile failure?
Think about what happens when a material is pulled apart.
How does concrete behave under tensile stress?
Remember the relationship between tension and strength.
What happens when tensile stress exceeds tensile strength in concrete?
Think about the breaking point of materials.
Tensile failure is a brittle failure. True or False?
Recall the abrupt nature of cracks.
A concrete beam is designed with a tensile strength of 2.5 MPa. A load is applied that creates a tensile stress of 3 MPa. What will happen to the beam? Explain the process leading to its failure.
Consider what occurs when the limits of material properties are reached.
Consider a scenario where a bridge made from concrete is being evaluated for tensile failure. Discuss the variables that could influence tensile strength under different environmental conditions and potential reinforcements that could be used.
Consider how external factors modify the material properties.
