Comparison of Mechanical Behavior of SiC Sintered Specimen to Analysis of Surface Defects
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2014)
Silicon carbide is the material that in sintered form is suiTab. for protection from impact as part of the multilayered structure. Its role is to accumulate energy from the projectile, to plastically deform the projectile ...
Modeling of the Mechanical Behavior of Fiber-Reinforced Ceramic Composites Using Finite Element Method (FEM)
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2014)
Modeling of the mechanical behavior of fiber-reinforced ceramic matrix composites (CMC) is presented by the example of Al2O3 fibers in an alumina based matrix. The starting point of the modeling is a substructure (elementary ...
