Q345C steel is welded under two different pre-welding heating methods of traditional flame heating and ceramic sheet heating.The finite element analysis of the butt joint weldment by ABAQUS software is used to summarize here the law of welding deformation and compare the welding quality under different pre-welding heating methods according to the r
The accurate description of fracture distributions is a crucial prerequisite for fracturing design and the evaluation of fracturing effects in tight reservoirs.We employed a fractal L-system to establish a tree branch model and derived a planar simulation method to characterize the distribution of natural weak discontinuities in rock.Weak discontin
Abstract Materials require special consideration when developing a project plan because they make up such a sizable chunk of the overall budget.Materials supply and delivery are crucial especially in road construction Neuw Rebel Skinny Eternal Black Jeans projects as they are required for the daily construction process.Lack of materials is a major
