Thermal barrier coatings (TBCs) are increasingly susceptible to degradation by molten calcium–magnesium alumino silicate (CMAS) deposits in advanced engines that operate at higher temperatures and environments laden with siliceous debris. This paper investigates the thermochemical aspects of phenomena using a model CMAS composition ZrO 2 –7.6%YO 1.5 (7YSZ) grown vapor deposition on alumina substrates. The changes microstructure chemistry characterized after isothermal treatments 4 h...
The thermochemical interaction between a Gd 2 Zr O 7 thermal barrier coating synthesized by electron‐beam physical vapor deposition and model 33CaO–9MgO–13AlO 3/2 –45SiO (CMAS) melt with melting point of ∼1240°C was investigated. A dense, fine‐grained, ∼6‐μm thick reaction layer formed after 4 h isothermal exposure to 1300°C. It consisted primarily an apatite phase based on 8 Ca (SiO ) 6 fluorite ZrO in solid solution. Remarkably, infiltration into the intercolumnar gaps largely suppressed,...
Two-dimensional meso-scale finite element models with realistic aggregates, cement paste and voids of concrete are developed using microscale X-ray Computed Tomography images. Cohesive elements traction–separation laws pre-embedded within aggregate–cement interfaces to simulate complex nonlinear fracture. Tension tests a large number images were simulated statistical analysis. The very different load-carrying capacities crack patterns demonstrate the effects random distribution phases. It is...
A procedure for generating two-dimensional heterogeneous meso-scale concrete samples is developed, in which the multi-phasic features including shape, size, volume fraction and spatial distribution of aggregates pores are randomised. Zero-thickness cohesive interface elements with softening traction–separation relations pre-inserted within solid element meshes to simulate complex crack initiation propagation. Extensive Monte Carlo simulations (MCS) uniaxial tension tests were carried out...
SUMMARY An automatic crack propagation modelling technique using polygon elements is presented. A simple algorithm to generate a mesh from Delaunay triangulated implemented. The element formulation constructed the scaled boundary finite method (SBFEM), treating each as SBFEM subdomain and very efficient in singular stress fields vicinity of cracks. Stress intensity factors are computed directly their definitions without any nodal enrichment functions. remeshing capable handling n ‐sided...
Flexible electronics is a cutting-edge field that has paved the way for artificial tactile systems mimic biological functions of sensing mechanical stimuli. These have an immense potential to enhance human-machine interactions (HMIs). However, still faces formidable challenges in delivering precise and nuanced feedback, such as achieving high sensitivity emulate human touch, coping with environmental variability, devising algorithms can effectively interpret data meaningful diverse contexts....
Size effect in concrete under tension is studied by Monte Carlo simulations of mesoscale finite element models containing random inclusions (aggregates and pores) with prescribed volume fractions, shapes size distributions (called meso-structure controls). For a given set controls, number realisations different spatial distribution are simulated to produce statistical data for macroscopic load/stress–strain curves. The complex meso-crack initiation propagation captured pre-inserted cohesive...
