Concept of Stress

Normal Stress
Normal Stress
Consider a rod subjected to an axial force; as a result, a resistive force is developed across the cross-sectional area, which is termed as stress. The SI ...
Contrainte de cisaillement
Contrainte de cisaillement
A structure when subjected to transverse forces develops internal forces in the sectional plane between the points where the forces are applied. The ...
Contrainte portante
Contrainte portante
The stress exerted on a material due to the contact pressure created while interacting with another object is called bearing stress. Consider two plates ...
Applications du stress
Applications du stress
Consider a structure consisting of a boom and a rod designed to support a load. The boom and the rod are joined by a pin and supported by brackets and ...
Contrainte sur un plan oblique
Contrainte sur un plan oblique
Consider a member subjected to axial forces. Introduce a sectional plane inclined to the normal plane, called an oblique plane. The stresses acting on ...
Contrainte : Conditions générales de charge
Contrainte : Conditions générales de charge
Consider a body subjected to multiple loads. When dissected through a point using a plane parallel to the xy plane, it is observed that the shearing ...
Composantes du stress
Composantes du stress
The stress components of a body subjected to multiple loading are analyzed by considering a small cube centered at point O. The cube has the normal and ...
Considérations relatives à la conception
Considérations relatives à la conception
While designing a structure, the considerations start with the ultimate strength of a material, which is determined through tests, measuring changes under ...
