Abstract—In this paper, analysis of an infinite beam resting on multilayer tensionless extensible geosynthetic reinforced granular fill-poor soil system overlying soft soil strata under moving load with constant velocity is presented. The beam is subjected to a concentrated load moving with constant velocity. The upper reinforced granular bed is modeled by a rough membrane embedded in Pasternak...

We present the design and development of a plant-inspired robot, named Plantoid, with sensorized robotic roots. Natural roots have a multi-sensing capability and show a soft bending behaviour to follow or escape from various environmental parameters (i.e., tropisms). Analogously, we implement soft bending capabilities in our robotic roots by designing and integrating soft spring-based actuation...

The aim of the thesis is to develop a numerical model based on first principles for the simulation of change of size of soil pores during drying of soft soil. This model is suitable for the type of soil consisting of clay with layered structure, such as Montmorillonite. In this study, the geometry of the soil pore is idealized by a triangle consisting of three sand grains and clay fabrics conne...

BACKGROUND AND AIMS The Finite Element Method (FEM) has been used in recent years to simulate overturning processes in trees. This study aimed at using FEM to determine the role of individual roots in tree anchorage with regard to different rooting patterns, and to estimate stress distribution in the soil and roots during overturning. METHODS The FEM was used to carry out 2-D simulations of t...

In this study, the performances of sand piles in Istanbul's Bağcılar and Zeytinburnu districts has been analyzed using Finite Element Method (FEM). Single group (triple) with various length/diameter ratios (L/D) were placed water-saturated soft clay soil. Sand modeled L/D (10, 5.71, 8.57). The distance between was chosen as 2 meters effect also investigated. A uniformly distributed load 162 kN/...

As NASA’s exploration missions on planetary terrains become more aggressive, a focus on alternative modes of locomotion for rovers is necessary. In addition to climbing steep slopes, the terrain in these extreme environments is often unknown and can be extremely hard to traverse, increasing the likelihood of a vehicle or robot becoming damaged or immobilized. The conventional driving mode in wh...

In this research paper, the dynamic analysis of complicated structures like nuclear reactor building has been done by considering the site specific response analysis. Analysis is done with and without considering the soil stiffness. First a Nuclear Reactor is considered which is resting on the ground surface and site specific ground response analysis for obtaining free field response of soft so...

The effects of a heavy travelling load on the soil medium and on the adjacent structures were studied. Five soil profiles were analyzed, three from sites in Southern California and two from well documented sites in Europe. It was found that the material damping in the soil layers does not affect attenuation, but rather radiation damping is the most significant. Four of the Five soil profiles st...

tunnelling through cities underlain by soft soil, commonly associated with soil movement around the tunnels and subsequent surface settlement. the predication of ground movement during the tunnelling and optimum support pressure could be based on analytical, empirical or the numerical methods. the commonly used earth pressure balance (epb) tunneling machines, uses the excavated soil in a pressu...

Soft clays are highly compressible, high-water content, low shear strength, and have poor permeability, which result in significant settlement under long-term loads. Therefore, one of the most challenging geotechnical engineering problems is to predict from soft clay soil. Normalized Rotational Multiple Yield Surface Framework (NRMYSF) developed soil stress-strain behaviour strength characteris...
