Micromechanics and structural response of functionally graded , 3 particulate - matrix , fiber - reinforced composites
24 Reinforcement of fibrous composites by stiff particles embedded in the matrix offers the 25 potential for simple, economical functional grading, enhanced response to mechanical 26 loads, and improved functioning at high temperatures. Here, we consider laminated plates 27 made of such a material, with spherical reinforcement tailored by layer. The moduli for this 28 material lie within relati...

Reinforcement of fibrous composites by stiff particles embedded in the matrix offers the potential for simple, economical functional grading, enhanced response to mechanical loads, and improved functioning at high temperatures. Here, we consider laminated plates made of such a material, with spherical reinforcement tailored by layer. The moduli for this material lie within relatively narrow bou...
متن کاملFracture Behavior and Properties of Functionally Graded Fiber-Reinforced Concrete
In concrete pavements, a single concrete mixture design is selected to resist mechanical loading without attempting to adversely affect the concrete pavement shrinkage, ride quality, or noise attenuation. An alternative approach is to design distinct layers within the concrete pavement surface which have specific functions thus achieving higher performance at a lower cost. The objective of this...
متن کاملCohesive fracture model for functionally graded fiber reinforced concrete
a r t i c l e i n f o Keywords: Concrete (E) Fiber reinforced concrete (FRC) (E) Constitutive relationship (C) Cohesive fracture (C) Fracture energy (C) A simple, effective, and practical constitutive model for cohesive fracture of fiber reinforced concrete is proposed by differentiating the aggregate bridging zone and the fiber bridging zone. The aggregate bridging zone is related to the total...
متن کاملFracture Analysis of Particulate Reinforced Metal Matrix Composites
A fracture analysis of highly loaded particulate reinforced composites was performed using laser moire interferometry to measure the displacements within the plastic zone at the tip of an advancing crack. Ten castings were made of five different particulate reinforcement-aluminum alloy combinations. Each casting included net-shape specimens which were used for the evaluation of fracture toughne...
