In the paper "Analysis the influence of particle size to the macroscopic behavior of Duplex Ferrite/Martensite steel with RVE method" ferrite–cementite steel sheets have been widely used in cold forming processing such as drawing, bending, and blanking. For the normal hot rolled steel sheets with ferrite and lamellar pearlite phases, the strength is usually too high and the hard lamellar pearlite will also cause cracking or tearing during cold deforming.

In study "Effects of different beam theories on dynamic response of BFGSW beams under a moving mass" effects of different beam theories on dynamic response of bidirectional functionally graded sandwich (BFGSW) beams under a moving mass are investigated in this paper. The core of the beams is homogeneous while their two faces are of three-phase bidirectional functionally graded material.

In ebook "In-situ small-angle X-ray scattering investigation of transient nanostructure of multi-phase polymer materials under mechanical deformation" the evolution of the materials structure is visualized and quantitatively analyzed from exhaustive sequences of scattering images. Three different classes of polymer composites are presented as typical and illustrative examples. The obtained results illustrate that the interactions of their components can cause unpredictable structural effects, ultimately leading to a weakening of the material, where a reinforcement was expected.

Microfluidics systems based on two-phase fluid dynamics have been widely applied from industrial machinery to the aerospace and automotive applications. The systems are designed to handle small volumes of liquids, often in the microliter or even nanoliter range. Droplet-based microfluidics is used for biochemical analysis or materials synthesis as well.

In this paper a generalized mathematical model was set up with the above factors taken into consideration. The mathematical model was then developed on a single-phase amorphous steel core transformer with a capacity of 3,3kVA-220V/115V to result in the degrees of deformation and vibration in cases with or without clamped iron for magnetic legs and yokes.

The Eastern Anatolian Fault Zone (EAFZ), having a prominent place in the tectonic evolution of the Eastern Mediterranean, is a structural element of tectonic indentor due to the convergence between the African-Arabian plates and the Eurasian Plate. This study investigates the central part of EAFZ between Doğanyol (Malatya) and Çelikhan (Adıyaman). The geometry of the fault and the morphotectonic structures were determined by the field studies. Moreover, fault-slip data are measured according to the fault planes along the deformation zone for paleostress analysis.

This paper proposes a new image processing model of the cardiac end-systolic and end-diastolic phase considered using image processing methods and for the segmentation of time series of medical images. This type of model is a unique design, since few attempt have been made to analyze the systolic heart interactions and diastolic relaxation using image processing methods.

This paper studies on improving strength of low-carbon steel via rolling deformation and dual-phase treatment. The results show that the dual phase treated steel has a combination of superior strength and good ductility. The tensile ultimate strength of dual phase treated steel reaches 740 MPa with fracture elongation of over 15%, while that of the cold rolled steel only reaches 700 MPa with fracture elongation under 3%.
