Controlled Precipitation of Calcium Carbonate in Spatial Dimension with Multiple Calcium Chloride and Sodium Carbonate Pulses
Controlled calcium carbonate precipitation can be used for various applications. Calcium carbonate precipitation occurs when dissolved calcium and carbonate are mixed at concentrations which exceed the solubility of calcium carbonate. With alternate injection of pulses of calcium chloride and sodium carbonate solution…
A Multiscale Framework for the Characterization of Damage in Textile Composites Under Thermomechanical Loads
This work examines composite failure at multiple scales. The first scale that is examined is the fiber-matrix scale, where fibers and matrix are discretely modeled. A model is developed at this scale which includes randomness in the fiber positions. This randomness is found to significantly influence the stress field and res…
Nanoindentation Measurements of Mechanical Properties of Very Thin Films and Nanostructured Materials at High Spatial Resolution
Nanoindentation can be used to assess bulk materials, coatings, and interfaces, but in many cases a composite response is produced that is influenced by the surrounding material. It is, therefore, essential to determine the correct test protocol to use if mechanical data that is generated is to be free of such influen…

Development of adhesives constitutive material laws for the assessment of bonded steel to glass partial composite beams
Glass products are widely employed in transparent facade and roof structures as tertiary non-structural elements despite their large in-plane compressive resistances. To structurally implement them in building, tensile stresses must be consequently reduced or avoided. The later requirements would be fulfilled by reali…
Improvement of wet and dry web properties in papermaking by controlling water and fiber quality
Pappersindustrin står inför många utmaningar och bör uppfylla krav som ställs av t.ex. marknadstrender och slutanvändare. Snabbare och effektivare processer ställer även större krav på pappersbanans mekaniska egenskaper. Avbrott i produktionen sker inte enbart pga. låg styrka utan orsaken kan även vara en för låg spän…
Graphene physics via the Dirac oscillator in (2+1) dimensions
We show how the two-dimensional Dirac oscillator model can describe some properties of electrons in graphene. This model explains the origin of the left-handed chirality observed for charge carriers in monolayer and bilayer graphene. The relativistic dispersion relation observed for monolayer graphene is obtained dire…

Mechanical and Microstructural Behaviors of Directionally Solidified Al2O3/Al16Ti5O34 Eutectics
In this work, rods of Al2O3–TiO2 eutectics containing 65 and 60 wt% Al2O3 were grown using the laser floating zone method. Raman spectroscopy was used to determine the phase composition. Creep strength of Al2O3–Al16Ti5O34 (65AT) eutectic at 1500°C has 320 MPa, which is about higher than β–Al2TiO5/Al2O3 (60AT) crystal.…

Early Considerations of Survivability in the Design of Naval Combatants – Blast Hardened Bulkhead and Integrated Box Girder Structural Vulnerability Reduction Measures – Part I (Blast Hardened Bulkheads)
Ship survivability has been defined as providing the capability of a warship to “Fight Through” damage. In the design of naval combatants, providing “Fight Through” capability is often achieved with structural vulnerability reduction measures such as blast hardened bulkheads and integrated box girders. Unfortunately,…

Non-Isothermal Crystallization Kinetics of Polyvinyl Alcohol-Graphene Oxide Composites
Polyvinlyl alcohol (PVA)/graphene oxide (GO) composites are prepared by solution blending method. And the non-isothermal crystallization kinetics of as-prepared composites is evaluated by differential scanning calorimetry (DSC). The results indicate the graphene oxide can significantly modify the non-isothermal crysta…
Solitons and thermal fluctuations in strongly nonlinear solids
We study a chain of anharmonic springs with tunable power law interactions as a minimal model to explore the propagation of strongly nonlinear solitary wave excitations in a background of thermal fluctuations. By treating the solitary waves as quasiparticles, we derive an effective Langevin equation and obtain their d…
Numerical analysis of transmission efficiency for parabolic optical fiber nano-probe
Theoretical calculations are performed for the transmission efficiencies of parabolic nano-probes with different shapes, based on the finite element method. It shows that the transmittance will fluctuate dramatically with the variation of either wavelength or probe shape, and the efficiency could be rather high even a…
Shear Wave Attenuation and its Micro-Mechanism of Polymers
The impact shear response of crystallized polypropylene under combined compression and shear loading was studied by using an inclined gas gun and electro-magnetic particle velocity gauges. The experimental results show that the transverse wave velocity increases nonlinearly with the impact velocity, indicating its she…
Special Features of Strain and Fracture in Steels under Impact Fatigue Loading
Processes of carbon steels fracture under their repetitive dynamic loading according to the compression scheme have been studied. It has been ascertained that the main cause of fracture of cyclically compressed specimens is crack initiation and propagation on exposure to tensile internal stresses forming at the crack…
Hardness of Laminated Composite for Different Angle Cured Positions under Influence of Gravity Effects
Utilization of high tech engineering materials such as composites has been extensively applied in the industries of civil, mechanical and aerospace due to their favourable characteristic such as high stiffness to weight ratio, improve corrosion and environmental resistance and potential reduction of processing. This r…
