The stress-strain curve describes the behavior of steel bars under loads. It is created by testing steel specimens. A steel specimen is gradually pulled through a testing machine until it breaks, and stress and corresponding strains are recorded. The stresses ...

What is Shear Center – Location of Shear Center with Examples
Shear center is a point on the beam-section where the application of loads does not cause its twisting. The shear center position is dependent on the cross-section of the beam. For instance, shear center and center of gravity are the ...
TYPICAL CASES OF AXIALLY LOADED STRUCTURAL MEMBERS
The wire in figure 1 is pulled by the action of a mass attached to its lower end. In this condition the wire is in tension. Suppose the total load on the cross-section of the wire is P and the ...
COMBINED BENDING, DIRECT AND TORSIONAL STRESSES
COMBINED BENDING, DIRECT AND TORSIONAL STRESSES IN SHAFTS Cases arise such as in propeller shafts of ships where a shaft is subjected to direct thrust in addition to bending moment and torsion. In such cases the direct stresses due to ...
TORSION OF SHAFTS
When a cylindrical shaft is subjected to equal and opposite couples at the ends, either it will be in equilibrium or it will rotate at a uniform rate. In either case, it is subjected to torsion and the stresses set ...
Theory of Simple Bending
When a beam is subjected to a loading system or by a force couple acting on a plane passing through the axis, then the beam deforms. In simple terms, this axial deformation is called as bending of a beam. Due to ...
FLITCHED BEAMS
Beams that are built of more than one material are called composite beams. Examples are bimetallic beams, which consists of two different metals bonded together, sandwich beams, and reinforced concrete beams. Composite beams may be analysed by the same bending ...
Determinate and Indeterminate Structures and Their DIfferences
Structure is generally classified into two categories as Determinate and Indeterminate Structures or Redundant Structures for analysis of structures to find forces based on criteria discussed below. Structure is an assemblage of a number of components like slabs, beams, columns, ...
