SUMMARY

The discussion focuses on calculating the stress along the tensile axis of a slender bar subjected to tensile loading and a constant compressive stress of 120 MPa in an orthogonal direction. The material properties provided include a yield strength of 320 MPa, Young's modulus of 120 GPa, and Poisson's ratio of 0.3. The participants emphasize the use of Tresca and von Mises criteria for determining the yielding stress, noting that the problem is straightforward and primarily involves identifying relevant information from the provided data.

PREREQUISITES
  • Understanding of tensile and compressive stress concepts
  • Familiarity with Tresca and von Mises yield criteria
  • Knowledge of material properties: yield strength, Young's modulus, and Poisson's ratio
  • Basic mechanics of materials principles
NEXT STEPS
  • Study the application of Tresca yield criterion in practical scenarios
  • Explore the von Mises yield criterion and its implications in material failure
  • Learn about stress transformation and its relevance in multi-axial loading conditions
  • Investigate the effects of Poisson's ratio on material behavior under load
USEFUL FOR

Mechanical engineers, materials scientists, and students studying mechanics of materials who are interested in yield criteria and stress analysis in structural components.

(need help with the following question)
A slender bar with rectangular cross section is subjected to tensile loading along its longitudinal direction. During the test, a compressive stress of 120MPa is always maintained in one of the two axes orthogonal to the longitudinal direction. The yield strength, Youngs modulus and Poisson's ratio of the material are 320MPa, 120Gpa and 0.3 respectively. Calculate the stress along the tensile axis that causes yielding predicted by the Tresca as well as von Mises criteria.

What's your question? This probably should be in the homework section.
 
Easy plug-and-chug problem, unless I'm missing something. I guess the difficulty is determining what information is relevant. Doesn't seem to me that "slender," "E," or "PR," are relevant for you, since the applied stresses are given.
