Response of soil depends on both the mechanical properties of soil itself and the nature of loading. Many geotechnical engineering problems are associated with dynamic and cyclic loadings, such as ocean wave or ice loading applied on foundations of offshore structures or bridges, dynamic loading applied on foundations of offshore wind power structures, ocean wave loading on harbor structures, s...

The main purpose of this paper is to investigate the stiffness of soils under cyclic loading at small and medium strain level. The influence of some important factors on the shear modulus of soils such as: the strain level, the plasticity index and the mean effective stress are discussed in detail. Behaviour of different kind of soils is also compared based on available laboratory data includin...

We explore the effect of microbial activity stimulated by root exudates on the penetrometer resistance of soil and its elastic modulus. This is important because it is a measure of the mechanical strength of soil and it correlates closely with the rate of elongation of roots. A sandy soil was incubated with a synthetic root exudate at different temperatures, for different lengths of time and wi...

Values of site factors in numerical simulation can have profound effects on the calculation accuracy. In order to fully understand the performance of rigid-pile composite foundation in tall buildings, this article set up an overall FEA model of a 25-storey frame-tube structure by considering the interaction of superstructure, foundation and ground. Thereafter, a detailed parametric study was pe...

In this article, a detailed study of the recently synthesized MAX phase borides M2SB (M = Zr, Hf and Nb) has been performed via first principles technique. Investigation mechanical hardness, elastic anisotropy, optical properties, dynamical stability thermal properties are considered for time. The estimated values stiffness constants moduli found in good agreement with available results. micro ...

In this paper, numerical analysis of a pile-soil interaction problem is presented considering the parameters influencing the axial load-deformation behavior of the pile embedded in a layered soil medium. The analysis is demonstrated with parametric solutions of a pile with underlain model soil strata under the axial force. An attempt is made to ascertain the extent of influence of elastic prope...

At present, 3D printing is experiencing a great boom. The demand for new materials also related to its expansion. This paper deals with manufacturing innovative polymer composite filaments suitable the Fused Filament Fabrication method in printing. As filler, common and uncostly glass beads were used mixed biocompatible biodegradable poly (ε-caprolactone), as matrix. material was characterized ...
