Victor Birman (vbirman@umr.edu)Introduction to the Course

The course will prepare the students to design columns, plates, shells and beam-columns. Inelastic buckling, effects of shape imperfections, and large deformations will be reviewed. Numerous application examples will be presented. Design equations and methods used in industry will be discussed.

Intended audience:1. Researchers: Theoretical

foundations of stability problems, their formulation and methods of solution;

2. Engineers: Identifying stability problems, solving “simple problems,” comprehending and interpreting FEA solutions.

Outline of the course:

Chapter 1: IntroductionChapter 2: Buckling of bars (columns)Chapter 3: Buckling of platesChapter 4: Buckling of shellsChapter 5: Beam-columns;Chapter 6: Torsional and lateral bucklingProjects: Four large industrial projects (designing structures subject to compressive loads). Students have 3 or 4 weeks to work on each project.

Projects will be defended in person or via e-mail/telephone. The performance of students is judged based on their projects. The projects replace homework assignments and tests.Course materials: Every student will receive a CD RAM disc with the copies of all slides used in the course. The students will also receive copies of relevant printed materials (free of charge).

Could a machine operate safely with cracks?

• All man made structures contain flaws or defects or cracks!

• The question is, could we design structures so that they operate safely in the presence of known or unknown flaws?

• Based on mechanics of materials approach, we cannot.

26

Mechanics of Materials Approach to Design

• MoM Approach assumes that materials and structures are “defect free”.

• Given two parameters, Applied Stress (loading) & Strength (material property)Applied Stress

YieldStrength

• Design stress ≤ Yield Strength

d = YS

27

Fracture Mechanics Approach to Design

• Fracture mechanics approach assumes that “all” materials and structures contain inherent “flaws/cracks” so failure occurs well below the static strength.

• Three parameters appear in the fracture mechanics design methodology: Applied Stress (loading), Fracture Toughness (material property) and Flaw size (quality control).

29

Fracture Mechanics - Objective

• Since we cannot build “defect free” structures, we would like to:

– Calculate safe load for a known defect– Determine safe defect size for a given load – select a material for a design load & defect– Determine “safe operating life” before a

defect grows and results in a catastrophic failure.

– Incorporate “damage tolerance” features so as to prevent catastrophic failures if an unexpected failure does occur

30

Fracture Mechanics - Objective

•To learn to deal/live with cracks!!!
