MicrobeWiki
MicrobeWiki is a free wiki resource on microbes and microbiology, authored by students at many colleges and universities. Curated pages such as those linked to the Taxonomy Index are reviewed and updated by microbiologists at Kenyon College. Student pages authored independently, or for coursework, are not monitored further. Featured Class: The University of Oklahoma Italian Center, taught by Tyrrell Conway. Educators: You may assign MicrobeWiki page creation and editing as projects for your students. BIOL 375 Virology, Joan L. Your students receive individual passwords. Microbial Mythology: common misconceptions and controversies in microbiology. Study Microbes presents study questions and recommended species for students to learn, based on the textbook Microbiology: An Evolving Science by Joan Slonczewski and John Foster (W.

Applied Mechanics of Solids (A.F. Bower) Chapter 9: Modeling Failure - 9.5 Plastic fracture mechanics
Chapter 9 Modeling Material Failure 9.5 Plastic fracture mechanics Thus far we have avoided discussing the complicated material behavior in the process zone near the crack tip. In this section, we address three issues: 1. 2. 3. 9.5.1 Dugdale-Barenblatt cohesive zone model of yield at a crack tip The simplest estimate of the size of the plastic zone at a crack tip can be obtained using Dugdale & Barenblatt’s cohesive zone model, which gives the plastic zone size at the tip of a crack in a thin sheet (deforming under conditions of plane stress) as where is the crack tip stress intensity factor and Y is the material yield stress. This estimate is derived as follows. and yield stress Y. should not exceed yield in this region. Let denote the length of the cohesive zone at each crack tip. , and distribute tractions of magnitude over the crack flanks from to , and similarly at the other crack tip.. along the line of the crack just ahead of each crack. must be chosen to satisfy . 1. 2. with . 1. 2. , strains
