Mass reduction channel

  1. Mar 23, 2013 #1

    Whilst working on a projected I encountered the following problem:

    I have a channel that is supported by two fixed supports. On this channel there are 6 loads, 2 on the side and 4 in the middle (see drawing).

    Obviously the shape will deform into a banana, and stresses will be highest in the middle.

    I want to reduce the weight of the channel. How can I find where I can "punch" holes in the material to lose weight (cut away non critical parts)? Does anyone have literature on this?

    And another question: how do I determine the siwe and shape of these holes (triangular, truss structure,...)?
