Description

Modelling elastic and plastic behaviour. Mechanisms of ductile/brittle overload, fatigue, creep and corrosion. Linear elastic fracture mechanics. Prediction of remaining life due to fatigue, creep, corrosive environments. Fracture safe design and fracture control plans. Correlation between chemical, structural and physical characteristics of metals and plastics necessary for appropriate material selection, design and processing.

This course builds on the structure-property-processing-performance concepts introduced in ENME207 for metals and polymers.  The focus on performance in ENME307 will aid students in complex design tasks in other courses such as ENME311 (proposed concurrently), ENME 401 and ENME 408 (both proposed new courses effective 2013).

Learning Outcomes

 Predict elastic and plastic deformation response.
 Apply brittle fracture safe design methods, including linear elastic fracture mechanics (LEFM) e.g., leak-before-break.
 Predict temperature effects on steels.
 Calculate remaining life due to fatigue, corrosion, environmentally assisted cracking and creep.
 Develop and apply fracture control plans.
 Apply methods for laboratory based failure analysis.
 Apply basic modelling concepts of viscoelastic materials to predict time-dependent properties (creep and relaxation), relaxation time.
 Perform dynamic mechanical analysis as a method for experimentally determining thermomechanical parameters.
 Perform analytical modelling and simulation of metal and polymer processing (injection molding, extrusion).
 Apply concepts of manufacture of metals and polymers in mechanical designs
