This comparison is referred to as the Equivalent Solid Material Concept. In an effort to provide designers with the information they need to make decisions about perforated metal, solid material equivalent tests were performed. The tests compared the strength of 26 different perforated metal samples to the equivalent solid metal. The samples tested are listed at the bottom of this page. In this test, the equivalent strength of the perforated material is used in place of the strength of the solid material.
Perforated material has different strengths depending on the direction of loading.
The values for the length direction have been calculated conservatively. All rights reserved.
