# Definition of Principal stresses | Principal plane | Principal Axis

Saturday, March 3, 2012 14:39 4 CommentsPrincipal stresses : Principal stresses may be defined as ” The extreme values of the normal stresses possible in the material.”

# Maximum Principal strain theory or Saint Venant theory with equation

Wednesday, February 8, 2012 16:09 No CommentsMaximum principal strain theory : This theory states that “ Yielding in a member subjected to complex/compound stress system commences when maximum principal strain of the system becomes equal to the strain corresponding to the yield

# Maximum principal stress theory of failure with equations

Sunday, February 5, 2012 8:57 No CommentsMaximum principal stress theory : This theory states that “A structural component will fail when maximum principal stress of the system will become equal to the yield strength of same

# Shear stress is zero at principal plane

Sunday, December 11, 2011 19:05 No CommentsProof of the statement “Shear stress is zero at principal plane.” At principal plane shear stress is zero. There is maximum direct or normal stress but no shear stress at principal plane.

# Derivation of the angle at which shear stress is maximum

Sunday, December 11, 2011 18:56 1 CommentDerivation of the angle at which shear stress is maximum: Shear stress is maximum at 45 degree from the principal plane. Below is the derivation of the angle at which shear stress is maximum.

# Shear stress equation on an oblique section of body

# Derivation of maximum normal stress at principal plane

Sunday, November 20, 2011 19:27 No CommentsDerivation of maximum normal stress at principal plane To find the maximum value of normal stress at some angle, we have to differentiate the normal stress transformation equation, (which we derived in the previous article) with respect to dθ. Principal Plane : It is the plane at which normal stress attains the maximum value. Below is […]
