CYPE 3D

Up until version 2024.f each element, panel or shell could be assigned to a single layer. As of version 2024.f each element can belong to several layers.

The tools for assigning parts, panels and shells to layers are unified in "Assign elements to layers". This tool allows you to select the type of operation and the display layers. The available operations are the following:

• Assign
  Adds the selected layers to the elements.
  
  
• Replace
  Replaces the previously assigned layers with the newly selected layers.
  
  
• Delete
  Deletes the selected layer from the previous assignment of each layer.

In layer management, the "Only draw the elements that intervene in the buckling analysis" option is included.

Using the new "Plastic hinges" option in the "Bar" menu, the relative position of the plastic hinges and their properties can be defined, as well as the rotational degrees of freedom in which they act.

The data required to define the behaviour of a plastic hinge at a given rotational degree of freedom are the plastic moment and the slope in the plastic section. The degrees of freedom are expressed in the local axes of the bar.

The properties of the hinge can be selected from those previously defined in the "Plastic hinge library" in the "Project" menu or entered directly in the plastic hinge definition panel.

The program can automatically analyse the value of the plastic moment for steel sections with a defined plastic modulus. In all other cases, this value can be defined manually.

In the forces view, the plastic hinges that have reached the plastic moment in the selected combination are highlighted by an increase in size and a colour change.
