This course is in three parts. Part one covers fundamentals of composites including estimating the mechanical and thermomechanical properties, failure of composites, laminate, and shear-lag model. Advanced topics including homogenization theories, Eigenstrain and Eigenstress, dilute, self-consistent and Mori-Tanaka methods are also covered. Part two covers fundamental of fracture mechanics including Griffith theory, stress field at crack tip, energy release rate, crack tip plasticity, and mixed mode fracture. Part three covers interface cracks, cracks approaching an interface, and fracture of composites.

Heterogeneous materials and composites are widely used in civil infrastructure. Examples of these materials include concrete, the most widely used construction material, and fiber reinforced polymers (FRP). It is essential for structural engineers therefore to understand the mechanical behavior as well as the failure and fracture of heterogeneous materials and composites.


This course covers mechanics and failure of quasi-brittle materials and brittle matrix composites, providing structural engineers with essential tools to estimate the properties of these materials and calculate the load capacity based on strength of material and fracture mechanics criteria. This course is needed because currently no existing course systematically covers mechanics and failure of quasi-brittle materials and brittle matrix composites.

College of EngineeringKara PetersI do teach MAE 537, Mechanics of Composite Structures. I think the proposed course content is different from 537, as we limit our discussion to fiber reinforced polymer materials. These are ductile matrix materials, as compared to quasi-brittle materials. There is no discussion of cementitious materials. Also, most of 537 is concerned with laminated composites, typical to what we see in the aerospace industry. We do discuss homogenization a little, but it is not a significant portion of the course
College of EngineeringJeffrey W. EischenKara has brought some good points that I agree with. The specific topics you mentioned in Part 2- fundamental of fracture mechanics including Griffith theory of fracture, stress field at crack tip, energy release rate, crack tip plasticity, and mixed mode fracture are all covered in my MAE543 course but the emphasis is on homogeneous isotropic materials. So if you are generalizing to other application areas I would support it.

Dr. Pour-Ghaz has offered this course in the past and plans to continue to offer it, and therefore no additional faculty resources are needed.

ABGS Reviewer Comments: Have the comments of Dr. Eischen's consultation been addressed?

ghodge 8/26/2015 Department may want to comment on how they determine a 500 vs 700 level course. Is this an elective in the CE program? Ready for ABGS board.
