Presentation Transcript

  1. EML 2023 – Stress Analysis Lecture 1 – Stress State

  2. Static Stress Analysis • The material we will cover in this topic will be studied in detail in the courses: • EGM 3520, Mechanics of Materials • EML 4500, Finite Element Analysis and Design

  3. Stress and Strain

  4. Loading conditions axial loading bending torsion

  5. Stress state the stress state at any point can be described by 6 values: three normal stresses and three shear stresses an orientation can be found such that there are no shear stresses the normal stresses are called the principal stresses

  6. von Mises stress • Von Mises defined a single value for the stress state at a point based on the six stress values • in terms of the principal stresses

  7. von Mises stress • design objective • at every point, keep the von Mises stress below the yield stress of the material
