Non-linear Finite Element Analysis of Cone Penetration in Layered Sandy Loam Soil: Considering the Precompression stress state
A computer simulation of cone penetration in layered soil was carried out using axisymmetric finite element (FE) to investigate soil deformation and soil hardpan prediction during cone penetration. The FE analysis was performed in ABAQUS, commercially available FE package. Soil was considered as a non linear elastic plastic material modeled using Drucker Prager material model with hardening op...
متن کاملEffects of Cultural Practices and Two Soilborne Pathogens on Root Morphology of Cotton in the Field
In many Arkansas cotton fields, factors such as inefficient tillage operations, extremely dry weather and traffic pressure may result in a compacted soil layer or hardpan. Soil compaction dramatically increases soil strength and can restrict cotton root penetration, leading to suppressed cotton height and lint yield (Taylor and Earl Burnett, 1963). This problem may be exacerbated by soilborne p...

متن کاملHardpan and Maize Root Distribution under Conservation and Conventional Tillage in Agro-ecological Zone Iia, Zambia
Hardpans (plough/hoe pans) are commonly believed to restrict plant root growth and crop yields under conventional small-scale agriculture in sub-Saharan Africa. This study questions the notion of widespread hardpans in Zambia and their remedy under conservation tillage. Soil penetration resistance was measured in 8x12 grids, covering 80 cm wide and 60 cm deep profiles in 32 soil pits. Large and...
متن کاملComparison of Tubular Penetration of AH26, EasySeal, and SureSeal Root Canal Sealers in Single-Rooted Teeth Using Scanning Electron Microscopy
Background and Aim: Tubular penetration of root canal sealers prevents filling material displacement and overgrowth of microorganisms in dentinal tubules. The aim of this study was to compare the tubular penetration of AH26, EasySeal, and SureSeal sealers in single-rooted teeth using scanning electron microscopy (SEM). Materials and Methods: Fifty human single-rooted teeth were included in thi...
