Thinwallres Open&Closed application allows to determine the resistance capacity of open and closed thin-walled sections. Determine the elastic and plastic stress state under a combination of stresses and their resistance capacity and for a set of combinations in the form of an interaction diagram. The plastic use of the sections allows optimization by reducing the cost of the structures.

Properties and Stresses of Thin-Walled Cross-Sections

SHAPE‑THIN determines section properties of any thin-walled cross‑section and calculates the stresses. In addition, you can perform plastic design.

Software for the design of open and closed thin walled sections elastic and plastic behavior. Takes into account axial and shear forces, bending moments, bimoment, torsional moment Saint venant and warping. Draws 3d sketch of elastic normal and shear stresses and von misses stress that can be rotated. Draws also plastic interaction diagrams up to 10 combinations taking into account the 8 internal forces (to draw the diagrams it takes about 5 five minutes). the help for more information
