Q. What is Extrusion defects?
• Surface cracking - When the surface of an extrusion splits. This is often caused by the extrusion temperature, friction, or speed being too high. It can also happen at lower temperatures if the extruded product temporarily sticks to the die.
• Internal cracking - When the center of the extrusion develops cracks or voids. These cracks are attributed to a state of hydrostatic tensile stress at the centerline in the deformation zone in the die.
• Surface lines - When there are lines visible on the surface of the extruded profile.
This depends heavily on the quality of the die production and how well the die is maintained, as some residues of the material extruded can stick to the die surface and produce the embossed lines.
whats the example of opportunity cost?
A rectangular block of material is subjected to stresses 65N/mm 2 (tensile) in x- direction and 35 N/mm 2 (tensile) in perpendicular direction. It is accompanied by shear stress
