Abstract The in-plane thermoelastic response of curved beams made porous materials with different types functionally graded (FG) porosity is studied in this research contribution. Nonlinear governing equations are derived based on the first-order shear deformation theory along nonlinear Green strains. solved by aid Rayleigh–Ritz method Newton–Raphson method. modified rule-of-mixture employed to...

Even if cement is a well-consolidated material, the chemistry of (and inside cement) remains very complex and still non-obvious. What sure that hydration mechanism plays pivotal role in development cements with specific final chemical compositions, mechanical properties, porosities. This document provides survey behind such inorganic material. The text has been organized into five parts describ...

Accurate modeling of windbreaks is essential for the precise assessment wind protection performance. However, in most windbreak studies, models used approximate shape simulated trees, resulting significant differences between results and actual situation. In this study, terrestrial laser scanning (TLS) was to extract tree parameters, which were a quantitative structural model (AdQSM) recreate s...

A well-established constraint on the size of non-porous olivine grains or porosity aggregates consisting small from prominent narrow peaks in thermal infrared spectra characteristic crystalline silicates is reexamined. To thoroughly investigate peaks, we make theoretical argument for absorption and scattering light by non-porous, non-spherical particles, which followed numerical verification. O...
