The problem asks to find out whether the rod yields at points in section A according to the tresca and von mises criteria
P is 120N
Shear stress= VQ/It
shear stress= Tp/J
The Attempt at a Solution
I picked 2 points at section A.
The Tresca Critrion is given in the form of non continuous equations:
Max(½|σ1-σ2|,½|σ2-σ3|,½|σ3-σ1|) = k
How did they come up with the invarient equation
f(J2,θ) = 2√J2 * sin(θ+⅓π)-2k, θ from (0 to 60)
I am trying to find a difference between two versions of the Dang Van criterion on multiaxial fatigue.
Let's say that Dang Van 1 is the one that uses a critical plane and Dang Van 2 the one that uses the Tresca criterion (which means no critical plane)
I assume that the only...
