Thermal regimes of space composite structures. Part I

Beyond First Order Logic: From number of structures to structure of numbers: Part I

We study the history and recent developments in nonelementarymodel theory focusing on the framework of abstractelementary classes. We discuss the role of syntax and semanticsand the motivation to generalize first order model theory to nonelementaryframeworks and illuminate the study with concrete examplesof classes of models. This first part introduces the main conceps and philosophies anddiscu...

Formation of Poly(vinylidenefluoride) Nanofibers: Part I Optimization by Using of Central Composite Design

Poly(vinylidene fluoride) (PVDF) nanofibers were prepared via electrospinning process. Several different factors influence on this process and application of experimental design for its optimization is of great importance. The central composite design (CCD) was used for planning and optimizing of the experiments and also, the analysis of variance (ANOVA) was employed for the statistical va...

Deformation Characteristics of Composite Structures

The composites provide design flexibility because many of them can be moulded into complex shapes. The carbon fibre-reinforced epoxy composites exhibit excellent fatigue tolerance and high specific strength and stiffness which have led to numerous advanced applications ranging from the military and civil aircraft structures to the consumer products. However, the modelling of the beams undergoin...

Coupled Flow-thermal Scalable Process Modeling Simulations in Liquid Composite Molding of Composite Structures

Net-shape liquid composite molding (LCM) processes for the manufacturing of composite structures involve the permeation of a reactive thermoset polymeric resin through complex, fiber woven preforms. The physical behavior during the processing thus involves coupled multi-physics phenomena consisting of mass, thermal and species transport. The flow process models based on conservation of mass are...
