Spring 2018

Days/Time: TTh / 12:00-1:15 pm
Credit Hours: 3

Learning Objective:
Gain understanding of current methods to compute fracture and fatigue in engineering materials and structures.

Description:
Prediction of the failure of engineering structure employing computational methods. Continuum models for material failure in brittle and ductile materials. Cohesive zone models for material failure. Material parameter determination strategies. Numerical implementation of constitutive models in finite element codes. Applications to engineering structures on the macro-micro and nanoscale. Sp2018 Syllabus

Topics Covered:
1. Introduce concepts of computational methods for material damage fracture and fatigue. 2. Learn continuum mechanics concepts for description of material failure. 3. Learn about advanced constitutive equations for bulk and interface failure. 4. Learn how model material failure processes. 5. Learn how to develop and apply computational mechanics methods. 6. Apply these concepts to analysis of failure of engineering components at the macro and microscale.
