| Description: | Aims: To extend understanding of, and the ability to apply, plasticity methods for the advanced analysis of structures. Learning Outcomes: After taking this unit students should be able to demonstrate: On completion of this unit, the successful student will be able to analyse and design complex and non-standard steel and concrete structures at the ultimate limit state through the use of advanced plasticity theory. The student will also be able to demonstrate: * a systematic understanding of this knowledge, and a critical awareness of current problems and/or new insights, much of which is at, or informed by, the forefront of this area of professional practice; and, * conceptual understanding that enables the student to evaluate critically current practice and new developments, and propose new solutions. Skills: Intellectual skills * To understand taught material - taught Professional/Practical skills * An ability to design and analyse complex structures which cannot be considered readily using other structural engineering approaches - assessed Transferable/key skills * To communicate ideas verbally and in writing - facilitated and assessed. Content: Yield and failure criteria, 3-D Mohr's circle of stress, hydrostatic and deviatoric stresses. C-curves and the pi-plane. Tresca and von Mises yield criteria. The flow rule, normality and convexity. Mohr-Coulomb failure criterion. The upper and lower bound theorems. Shakedown. Torsion, indentation, axial and shear effects for metallic structures. Concrete plasticity, upper-bound flexural and shear analysis, lower-bound strut-and-tie methods. Soil plasticity, coupled shear and volumetric behaviour, and the CamClay model. |
