Analysis of Advanced Structures

Recommended Prerequisites

Strength of Materials, Elasticity and Plasticity, Mechanics of Structures, Linear Algebra, Mathematics Analysis  

Teaching Methods

The theoretical lectures aim to introduce the topics covered by the course. In the theoretical-practical classes, key-problems are solved by the students with tutorial supervision. Outside the classroom, students are encouraged to solve additional problems, complementary to those addressed in the classroom, to stimulate the autonomy. The finite element modelling of advanced structures is performed using commercial software. 

Learning Outcomes

The primary purpose of this course is to provide the students with a comprehensive understanding of the key concepts associated with the analysis of advanced structures. More specifically, the course provides students with skills that allow them to establish relationships for anisotropic elasticity; analyse the mechanical behaviour at micro and macro levels; select failure criteria and design methods; and develop numerical models for advanced structures.

Syllabus

1. Introduction: classification, terminology, applications and background concepts. 2. Macro-mechanical behaviour of a lamina: elastic anisotropy, constitutive relationships of anisotropic, monoclinic, orthotropic, transversally isotropic, and isotropic materials; hygrothermal effects. 3. Micro-mechanical behaviour of a lamina: constituent materials, volume fraction, mass fraction, density, and void and porosity contents; relationship between properties of constituent materials and properties of composite materials; experimental determination of mechanical properties; classical theory of laminate beams; first order theory. 4. Macro-mechanical behaviour of a laminate: stress-strain relationships; hygrothermal stress-strain relationships; failure criteria; environmental effects; impact resistance, fracture resistance, and fatigue resistance; numerical modelling using the finite element model; cases study.
