Force Needed To Dent A Sheet Of Aluminum

The goal here is to drill only through the aluminum not the house underneath.

Force needed to dent a sheet of aluminum.

A wooden dolly block may be employed in more critical situations where a greater downward driving force is needed for a very specific change in shape. Multiply x 1 60 a36 steel recycled. Use a 1 8 inch bit or a similar size. Dent an aluminum can and it will be easier to crush from top to bottom.

Use a putty knife to scrape the surface level with the siding. The exact size isn t important. An aluminum vessel of equivalent design strength will be considerably less easy to dent a plus and will have approximately the same ultimate failure point. The oil canning critical buckling load increased with the increase in drop velocity and initial and secondary stiffnesses decreased with the increase in drop velocity for both steel and aluminum.

Multiply x 36 brass 1 4 hard. Sand the patch to remove all roughness and paint it to match the siding. For the aluminum alloys the denting force increased with the drop velocity at lower velocities and decreased or remained unchanged at higher velocities. A sheet of twice the strength but half the thickness will generally have poorer dent resistance than the original sheet.

Straightening tempered aluminum sheets. Dent resistance is a primary design criterion for auto body exterior panels. Calculating and determining the correct force involves factors and considerations such as the width and thickness of the metal and the diameter of the bending machinery. Multiply x 1 25 stainless steel.

Another way of viewing its lesser resistance to flexure and of understanding the primary requirement for rigidity of structure. But predicting the exact force needed to crumple a dented can is notoriously difficult requiring knowledge of the exact dimensions and position of the flaw. Crashworthiness is also highly dependent on how the materials construction and design of the vehicle work together. Determine the tensile strength of the metal sheet or t in units of pounds per square inch.

Stretching hot shrinking annealing metal finishing. Drill a small hole in the center of the dent. As a example assume t is 20. Multiply x 52 high carbon steel.

Refer to the metal documentation or specifications. To calculate the tons needed for other metals just multiply number times the tons required for punching mild steel. Using sandpaper take off all the paint. Fill the dent with the two part auto body filler.

Multiply x 70 copper 1 2 hard. When the paint dries your siding will look like new.
