“…Composites and components made of composite materials can be manufactured using multiple technologies. The choice of technology depends on the shape of the component being manufactured, the requirements for its mechanical properties, the structure and surface quality, the cost of manufacturing the product and the required productivity [4]. Methods for producing composite materials are [5,6,7]: -applying the liquid matrix to the surface of the fibers, -powder metallurgy (cold pressing and subsequent sintering), -vacuum or pressure impregnation of the reinforcement by the liquid matrix, -infiltration of the fibers with a liquid matrix from the bottom side, from the top side and combined (pouring, filling or immersion of the reinforcement), -wetting of the reinforcement in the matrix and its subsequent shaping, -hot pressing (the matrix melts during hot pressing and the reinforcement is distributed in its volume), -hot rolling (during continuous lamination by inserting a reinforcement placed between the sheets of the matrix), -spraying a matrix with discontinuous reinforcement, -gas phase infiltration (foam composite materials), -infiltration of liquid reinforcement (coating of porous materials), -electrolytic metal deposition.…”

By 3D printing it is possible to create different structures with different fiber-laying directions. These structures can be created depending on the type of 3D printer and its software. The Mark Two printer allows printing Onyx, a material based on nylon in combination with microcarbon fibers. Onyx can be used alone or reinforced with kevlar, glass or carbon fibers. This article deals with 3D printing and evaluation of mechanical properties of printed samples.

“…Salah satu faktor yang perlu diselidiki pada pengujian lelah adalah besar beban yang mempengaruhi batas lelah logam yang dihitung hingga memampu mencapai umur siklus (N f ) antara 10 7 atau 10 8 [6,14]. Pengujian lelah dilakukan menggunakan siklus putar berfrekuensi rendah dengan rentang frekuensi antara 10 hingga 200 Hz.…”

The addition of Silicon (Si) on the gray cast iron can initiate graphite dispersion where the graphite becomes smaller and more evenly distributed. This study investigated the effect of Si concentration of 2.9% and 3.8% on the fatigue strength of the gray cast iron. The Si was added by the casting process with the open ladle method. The specimens were manufactured by following the ASTM E-466. Several tests such as tensile test, Brinell hardness test, and microstructure observation were conducted prior to the fatigue testing. The results showed that the Si concentration of 3.8% tended to increase the tensile strength up to 1.3%, the hardness up to 7.6%, and fatigue limit up to 10%. Moreover, the fatigue fractured specimen of 3.8% Si showed the combination of type A and type B graphite where graphite is smaller and more evenly distributed. In addition by applying the logistic equation, the fatigue strength can be predicted well.

“…These transformations cause large plastic deformations of the reinforcement, which cause the loss of cohesion with the concrete. Concrete reinforcements produced by cold drawing have a non-significant yield stress value therefore  0.2 is used [1,3,9].…”

The paper deals with the finite-element analysis of damage in reinforced concrete beam and prestressed reinforced concrete beam. The steel reinforcement is modeled using non-linear rebar elements and an elastoplastic model of the reinforcement is considered. The initial prestress is defined in the ropes that are used to create the prestressed reinforced concrete beam. These ropes are also modeled using non-linear rebar elements and the elastoplastic material model. Created computational model allows the damage modeling of the reinforced and pre-stressed reinforced concrete beams under static loading.
