The Three B's: Bend before Break - Does It Matter?

When the Apple iPhone 6 and 6 Plus were released last year, they were all the rage - lighter, faster, and bigger. Soon after, reports about phones being bent started coming out. But is bending really a bad thing?

One of the reasons for bending is ductility, which is the ability of materials to deform under load. These materials can have substantial plastic deformation before actual failure. Contrast this with the similar curve for a brittle material, such as glass, which shows little or no plastic deformation and fails without warning. Here is a comparison of the stress-strain curve for ductile and brittle materials. See the difference in the area under the curve which shows the amount of energy that can be absorbed (elongation) before failure.

In a recent webinar, we asked users which activities take most of their time. The answer was creating and modifying the model.

Let’s dig deeper. Which of these tasks consumes most of your time?
 
  1. Initial model creation
  2. Specifying material data – including creating your own materials
  3. Verifying input for correctness
  4. Moving support locations
  5. Modifying geometry – adding a loop
  6. Other

Define global coordinates for specific node points by pressing ALT+G in the Piping Input.

You can use global coordinates for many purposes. For example, you can:
  • Evaluate environmental loads (such as assessing wind/wave loads to determine element elevations).
  • Define actual coordinates for elements that are listed in the Coordinates List Input.
  • Run multiple models in the same CAESAR II job (by offsetting them).
