Concrete Under Multiaxial Loads

Concrete Under Multiaxial Loads

NDE of Concrete . Behaviour of concrete under various loads. Concrete very rarely undergoes a crushing or compression failure. Typically, tensile strains generated in the lateral direction (perpendicular to the loading direction) due to Poisson effect are responsible for cracking leading to failure of concrete.
