Chapter 16: Composite Materials
• Post-tensioning is the method of achieving pre-stressing after the concrete has hardened and takes advantage of concrete's inherent compressive strength. • Concrete is exceptionally strong in compression, but generally weak when subjected to tension forces or forces that pull it apart. These tension forces can be created by Chapter 16 -11

OVERVIEW OF HEURISTIC OPTIMIZATION
web.eng.fiu.eduOPTIMIZATION (Eberhart Kennedy -1995) A robust stochastic optimization technique inspired by the social behavior of swarms of insects or flocks of birds –maximize “food”. Apply the concept of social interaction to problem solving. Developed in 1995 by James Kennedy (social-psychologist) and Russell Eberhart (electrical engineer).
Experiment One (1) Tensile Stress Testing
web.eng.fiu.eduor Pa). In Equation (3.3-2), å is the strain measured in in/in (m/m) in the direction of the applied load. Since strain is dimensionless, the elastic modulus is measured in units of psi (Pa). It is important to realize that Equations above is valid only for uniaxial tension and is a special case of a generalized set of relations known as Hooke ...
