Composite Beam Analysis Example (Part 2) - Mechanics of Materials
 
16:29
An example problem solving for normal stresses due to internal moment in a simply supported composite beam using the transformed area method. Part 2 of the video covers the following topics: 1) Calculating normal stresses with flexure formula of the transformed section (or area) 2) Drawing the normal stress profile of the transformed section 3) Drawing the normal strain and stress profile of the composite section. The important part is the discussion between the relationship between the stress profile of the transformed section and the composite section.

SFCM 11/12 1: Discrete damage mechanics for laminated composites
 
59:41
Lunes 10 de Octubre de 2011 EVER J. BARBERO - College of Engineering and Mineral Resources, West Virginia University, USA A damage constitutive model incorporated into FE commercial software is proposed for predicting onset and evolution of matrix cracking and stiffness reduction of composite laminates with otherwise arbitrary stacking sequence. Lamina crack densities are used as state variables, with crack growth driven by both mechanical and thermal stresses. Lamina moduli and critical strain energy release rates GIC and GIIC are the only properties needed for predicting both initiation and evolution of damage, without any additional adjustable parameters. Strain localization, mesh size dependence, in-situ adjustment of strength data, and/or characteristic length, are avoided by the proposed analytical stress-displacement formulation. Predicted values of crack initiation, evolution, and stiffness degradation will be presented along with to experimental data.

Mechanics of Composites Lab - First translaminar fracture toughness model for composites
 
02:12
Produced for the Mechanics of Composites Lab in the Department of Aeronautics at Imperial College London. "Using a fundamental understanding of the physical processes underlying failure of composite materials, we stand to not only to design more efficient lightweight structures, but also to design improved composite micro-structures with bespoke mechanical response. We aim to deliver world-leading research on the experimental investigation, analytical modelling and numerical simulation of the mechanical response of fibre-reinforced composite materials. Our group consists of passionate, creative and committed researchers, which pursue excellence on every aspect of their research." By noticing the key role played by hierarchy in the fibre tensile failure mode in UD plies, the group developed the first analytical model in the literature that is capable of predicting the translaminar fracture toughness of UD plies. This model can be used not only for structural design, but also for material development, since the predictions are obtained from fibre / matrix / interface properties.

Mechanics of Composites Lab - First Ply-Level Translaminar Fracture Toughness Test

"Using a fundamental understanding of the physical processes underlying failure of composite materials, we stand to not only to design more efficient lightweight structures, but also to design improved composite micro-structures with bespoke mechanical response. We aim to deliver world-leading research on the experimental investigation, analytical modelling and numerical simulation of the mechanical response of fibre-reinforced composite materials. Our group consists of passionate, creative and committed researchers, which pursue excellence on every aspect of their research." - Dr Silvestre Pinho, Lab Leader. Home Contributions Projects Recognition People Constitutive Models Fracture Toughness Test Fracture Toughness Model Recycled Composites Numerical Models Periodic boundary conditions Translaminar fracture of a composite UD ply leads to energy being dissipated by splitting (a form of matrix cracking), friction (during the pull-out of fibres), fibre fracture (which is counter-institutively negligible at least in most cases), as well as local delamination. While the fracture surface is complex at he microscopic level, from a mesoscopic point of view it is possible to regard the fracture surface as a homogenised fracture plane. The question then becomes: what should the fracture energy associated with the formation of this fracture plane be? The answer to this question is relevant for numerical models that include these homogenised cracks and for the comparison of different material systems. In 2002-2004, when developing the first regularised smeared-crack model for laminated composites, the group needed ply-level translaminar fracture toughness values. At the time, these toughnesses did not exist even as a concept. Since then, the group has developed and perfected experimental tests to measure translaminar toughness in tension and compression, for UD and woven plies, for plies with fibres at an angle, and the group has demonstrated how the toughness depends on the thickness of the plies.

Composite Materials Overview for Engineers Register for Composite Materials Overview for Engineers at https://www.edx.org/courses Introduction of composite materials from engineering design, manufacturing, and repair viewpoints. About this Course Composites are used in many industries today to enable high-performance products at economic advantage. These industries range from space to sports and include manufactured products for aircraft, transportation, energy, construction, sports, marine, and medical use. There are many material, economic and aesthetic advantages to using composites, but a solid knowledge of the physical properties, including the mechanics, tooling, design, inspection & repair, and manufacturing options is required for working in this medium as they are intrinsically linked. This course provides an introduction to the fundamentals of composite materials for high performance structures from the point of view of Aerospace engineering design, manufacturing, and repair. It is designed to address critical areas of composite technologies that focus on materials, manufacturing, mechanics, design, inspection, and repair. In this course students will learn how composite materials achieve properties of strength, weight ratios and durability that surpass aluminum in aircraft design. For these high performance applications engineers typically rely on laminated structures, which are built up from many varying layers of ply-materials. Using this process the mechanical properties of the composite part can be tailored to specific applications resulting in significant weight and cost savings. Tailoring specific properties and designing innovative laminate structures highlights the multidisciplinary nature of this industry and how it touches the expertise of many disciplines including engineers, mechanics, and inspection specialists. After successfully completing this course, students will be able to identify the unique characteristics of composites and understand how advanced composite structures are designed, manufactured and maintained. When you have finished this course, you will be able to: Demonstrate understanding of fundamentals in materials, manufacturing, mechanics, design, and repair of polymeric matrix composites Identify advantages and disadvantages of polymeric matrix composites with respect to metals Apply the knowledge acquired to the design and manufacturing of high performance composite structures
