the dynamic response of the railway under accelerated moving load using dynamic green function is presented in this paper. for this purpose, an exact and direct modeling technique is introduced for the railway modeling as the damped euler-bernoulli beam on the partial winkler foundation with arbitrary boundary conditions subjected to the moving load. the effects of the elastic coefficient of wi...

Climate change, through changes in temperature, precipitation, and frequency of extreme events, has influenced agricultural production food security over the past several decades. In order to assess climate weather-related risks fruit grape Serbia, bioclimatic indices occurrence unfavourable weather events are spatially analysed for two decades (1998–2017) standard climatological period 1961–19...

The mechanical contribution of plant roots to soil strength has typically been studied at the ultimate limit state only. Since many geotechnical problems are related serviceability, such as deformation infrastructure, a new constitutive modelling framework is introduced. rooted treated composite material with separate relationships for and roots, comprehensive stress–strain relationship root co...

A novel exact analytical solution is derived for the equation y(4)+xny=0 in region x≥0, which important analysis of piles soil with stiffness varying depth. To date, solutions long are available only cases where n=−4, 0, and 1. For other values exponent n, have formerly been obtained numerically, mainly by finite-difference method or approximate solutions. An inherent difficulty obtaining beams...
