الملخص الإنجليزي

This study has been carried out at two stages, the first covered test and analysis of finite element method and Ansys program was used in the analysis.

Maximum stress Von-mises stress and deflection were adopted.

In the second stage the performance evaluation of the plow Three shapes of plow shares were used for comparison; conventional, locally manufactured (Hoe and notched) and two levels of depths (10-20) cm and (20-30) cm.

The tests have been carried out in soil (loam) with moisture content of (13.99(%.

The following factors were investigation; maximum stress, soil resistance force to cut consistency, energy utilization efficiency, , soil distribution volume and coefficient of working width exploitation.

Results showed showed that the notched share has the lowest value of stress and deflection and , soil resistance force to cut consistency, and higher values energy utilization efficiency and coefficient of working width exploitation and soil distribution volume , of the Hoe share showed higher values of stress and deflection and soil resistance force to cut consistency and lowest value energy utilization efficiency ,the depths (10-20) cm showed higher values energy utilization efficiency and coefficient of working width exploitation ,wheel the depths (20-30) cm showed higher values soil resistance force to cut consistency and soil distribution volume.
