Using calculations on defective graphene from first principles, we herein consider the dependence of the properties of the monovacancy of graphene under isotropic strain, with a particular focus on spin moments. At zero strain, the vacancy shows a spin moment of 1.5 $μ_B$ that increases to $\sim$2 $μ_B$ when the graph…
Abstract Surface engineering techniques are being used extensively in the aerospace and space industries as well as a variety of other industries to develop, maintain, or change a wide range of functional properties, including physical, chemical, electrical, electronic, magnetic, mechanical, wear‐resistant and corrosi…
Abstract The survivability of a platform in the battlefield is based on three issues – damage avoidance, damage tolerance, and damage repair. The design of a platform, in this case an aircraft, must consider in a balanced manner all three elements in order to reduce the chances of loss of the aircraft from the battle…

Disertační práce se zabývala vlivem adheze mezi vláknovým (FRC) a částicovým (PFC) kompozitem a složením obou komponent na mechanické vlastnosti a způsob porušování modelových bi-materiálových kompozitních těles při statickém namáhání. Zkoumán byl také vliv způsobu přípravy bi-materiálového kompozitního tělesa na pevn…
Abstract The group of translaminar‐reinforced composites, which includes stitched and Z‐pinned materials, requires additional manufacturing step (insertion of a stitch thread or Z‐pin) after the in‐plane fiber architecture has been already formed. This is why this group suffers from in‐plane fiber damage, distortions…
Abstract A composite overwrapped pressure vessel (COPV) is a thin liner overwrapped by fiber reinforced polymer matrix composite material (FRPMC) through either wet filament winding process or layup with prepegs. Because of the weight benefit, space shuttle and International Space Station used COPVs for the storage of…
Abstract Guidelines on the development of a successful test plan for large‐scale, aerospace vehicle shell buckling tests with particular attention given to defining test objectives and requirements are presented. In addition, some of the more challenging aspects of test planning, test operations, test article, and tes…

The ploughing effect appears frequently in machining. It influences the quality of machined surface, tool life and dynamical behavior of machining system. But modeling of ploughing is difficult as it is always coupled with the cutting effect. Nevertheless there could be found different ploughing models in scientific l…
Abstract Following a brief history of superplasticity leading to work that demonstrated the feasibility of combining superplastic forming (SPF) and diffusion bonding (DB) of α/β Ti alloys, the characteristics and the requirements for SP behavior are outlined. The importance of a high‐strain‐rate sensitivity, ormvalue,…
Abstract Aluminum alloys have a wide range of applications in the aerospace industry due in part to a high strength to weight ratio and resistance to corrosion. The relatively low melting temperature of these materials makes them amenable to variety of fabrication methods. Critical to the usage of these materials for…
Abstract The effect of hypervelocity impacts from micrometeoroids and orbital debris (MOD) on spacecraft materials and structures is discussed in terms of observed flight damage and laboratory simulation tests. Methods of estimating the probability of impact as a function of particle size are presented based on partic…

Abstract Ligh‐weight sandwich structures are utilized for their relatively high specific bending rigidity and strength. In addition, the core material can be selected to optimize the performance of the structure with respect to various transport phenomena such as fire retardation, thermal conduction, and sound transmi…
Abstract Metal matrix composites offer the potential for improved specific properties as well as increased elevated temperature performance relative to their unreinforced alloys. These are critical attributes for many aeroengine applications, making composites attractive despite their higher cost. For brittle matrix s…
Abstract Intermetallic titanium aluminides offer an attractive combination of low density and good oxidation and ignition resistance with unique mechanical properties. Thus, they are one of the few classes of emerging materials that have the potential to be used in demanding high‐temperature structural applications wh…
Abstract The last decade has seen the maturation of textile methods for making ceramic matrix composites with three‐dimensional (3D) fiber‐reinforcement. Such composites are much less vulnerable than traditional two‐dimensional (2D) ceramic composites to premature brittle failure, especially via delamination. Innovati…
