Damage Analysis of Moldboard Plow

Draft and drawbar power equirement of moldboard plow in a clay loam soil

comparison of a three-harrow two-way square plow with a three-harrow one-way moldboard plow

a one-way moldboard plow turns over soil in only one direction. problems created by this type of tillage in iran include compaction of boundary regions, decreased efficiency of irrigation and disruption of bed leveling, requiring the use of bed-leveling equipment every few years. to overcome these problems, the use of a two-way plow with two harrows which turns over the soil to both the left an...

Design, Development, and Performance Evaluation of a Trash-Board Moldboard Plow for the Interaction between Soil and Straw with Two Different Water Content Levels

A two-year field study was conducted to investigate the performance of a lightweight trash-board moldboard plow (with and without a trash-board), as influenced by stubble height and water content. Both fields were measured for the performance of a trash-board moldboard plow when used during the optimization of the plowing depth, the water content, and the reaction forces. The results showed tha...

‌Progressive Damage Analysis of Laminated Composites using Continuum Damage Mechanics

In this paper, progressive damage and global failure of composite laminates under quasi-static, monotonic loading are investigated using 3D continuum damage mechanics. For this purpose, a finite element program has been developed using an eight-node 2D layered element including layer-wise plate theory. Damage analysis of a single orthotropic layer under various uniform in-plane and transverse l...

Mow-plow crop residue management in ̄uence on soil erosion in north-central Oregon

Soil loss from dryland farms on the Columbia Plateau in Oregon and Washington (USA) results primarily from rain falling on frozen, cultivated soil. Soils are most susceptible to erosion when moldboard plowed, summer-fallowed, repeatedly rodweeded or cultivated, and fall planted to winter-wheat. These tillage practices are used because they help control weed and disease infestations and consiste...
