Accurate estimates of stress in an atherosclerotic lesion require knowledge the material properties its components (e.g., normal wall, fibrous plaque, calcified regions, lipid pools) that can only be approximated. This leads to considerable uncertainty these computational predictions. A study was conducted test sensitivity predicted levels and strain parameter values plaque used finite element analysis. Results show stresses within arterial pool have low sensitivities for variation elastic...
Abstract Most rocks show different elastic properties in tension and compression (bi-modularity). In this study, we derive new equations to calculate the tensile Young’s modulus Poisson’s ratio from a Brazilian test by incorporating bi-modularity into stress–strain equations. We tested specimens of Lac du Bonnet granite compared obtained with values direct tests on dog-bone shaped specimens. Digital image correlation (DIC) conventional strain gauges were used extract flat surfaces disks....
Numerical modelling is playing an increasing role in the interpretation of geological observations. A similar phenomenon occurring with respect to stress–strain response intact rock measured laboratory tests. In this research, three-dimensional (3D) bonded particle model (BPM) flat-jointed (FJ) contact was used investigate impact stress paths on failure. The modified FJ for these studies numerically captured most behavior Lac du Bonnet granite observed laboratory. numerical simulation track...
We have considered the problem of flow through a suddenly-expanded channel and performed computational investigation to examine numerical effects on prediction instability bifurcation phenomena. The results revealed that solution depends method employed. employed Godunov-type methods in conjunction with first-, second- third-order accurate interpolation schemes. It is shown order accuracy used discretisation wave-speed dependent term averaged part intercell flux affects instability....
Galvanization is the process of applying a protective zinc coating to steel or iron in order prevent premature rust and corrosion. Proponents galvanized steel, who may use it construct repair structures, for example, benefit from lower maintenance costs because its special properties Without protection, will due atmospheric conditions over time.
The paper presents a numerical study of incompressible fluid flow through micro-channels. Using high-resolution method (second-order accurate) in conjunction with non-linear multigrid algorithm and the pseudo-compressibility approach, we have investigated micro-flows straight channels, as well sudden contraction-expansion geometry. For channel geometry, computational results are reasonable agreement experimental data for various low Reynolds numbers. reveal transition to instability. This is...
Mathematics is a big driver in addressing the world’s complex problems, such as feeding growing population, ethical use of artificial intelligence, and environmental sustainability. Previous research has established that due to COVID-19 pandemic, many students suffered learning loss, particularly math. The gap math education pandemic socioeconomic inequalities will have long-lasting implications for students, contributing lack career opportunities increasing income disparities. This study...
The accurate assessment of rock mass strength and the failure zone near excavation is important for rational design underground structures. To predict behaviour during excavations, generally, two most widely used criterion namely, linear Mohr-Coulomb nonlinear Hoek-Brown criteria are used. However, envelopes from deviate much, especially, at low confinements. main motive this investigation to understand stress state around an opening. An copper mine Hindustan Copper Limited (HCL) i.e.,...
