Question
Download Solution PDFIn a two-dimensional stress system, the principal stresses are σ1 = 200 N/mm2 (tensile) and σ2 (compressive). The yield stress in compression is 250 N/mm2, with μ = 0.25. What will be the value of σ2 according to the maximum normal strain theory?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:
According to maximum Normal Strain (principal strain) theory:
Maximum principal strain due to loading = maximum principal strain due to elastic limit
σ1 – μσ2 = fy
Wherein,
σ1 and σ2 are principle stresses and fy is the yield stress
Calculation:
Consider tensile stresses positive and compressive stresses negative.
Given,
σ1 = 200 N/mm2 (tensile) ; σ2 = σ (Compressive) ; μ = 0.25; fy = 250 MPa
⇒ σ = 200 MPa
