Prerequisites 

ENES 102
MATH 141
PHYS 161

Description 

  • Stress and deformation of solids-rods, beams, shafts, columns, tanks, and other structural, machine and vehicle members. Topics include stress transformation using Mohr's circle; shear and moment diagrams; derivation of elastic curves; and Euler's buckling formula. Design problems related to this material are given in lab.
  • Requirement for the following UMCP engineering programs: Aerospace Engineering; Bioengineering; Civil and Environmental Engineering; Fire Protection Engineering; Mechanical Engineering.

Goals 

The student will develop and/or refine their knowledge in the following areas:
  • Stresses and deflections in shafts
  • Stresses in beams – bending and shear
  • Beam deflections using singularity functions and superposition
  • Statically indeterminate rods, shafts, and beams
  • Thermal stresses and deflections in rods
  • Stress transformation and principal stresses using Mohr’s circle
  • Material failure theories
  • Stress analysis under combined loading – 2D and 3D
  • Eccentrically loaded columns
  • Stress concentrations under static and fatigue loadings
  • Linear elastic fracture mechanics for static loadings

Topics 

  • Moments of inertia for plane areas
  • Stresses and deflections in shafts
  • Stresses in beams – bending and shear
  • Beam deflections using singularity functions and superposition
  • Statically indeterminate rods, shafts, and beams
  • Thermal stresses and deflections in rods
  • Stress transformation and principal stresses using Mohr’s circle
  • Stress analysis under combined loading – 2D and 3D
  • Column analysis
  • Stress concentrations and fatigue strength

Learning Outcomes 

  • an ability to apply knowledge of mathematics, science, and engineering
  • an ability to function on multi-disciplinary teams
  • an ability to identify, formulate, and solve engineering problems

Class/Laboratory Schedule
