Welded connections

Compared to other sectors, mechanical engineering is usually responsible for verification itself, i.e. it is often not regulated. Nevertheless, the calculation is part of the verification obligations of the engineer and designer.

MDESIGN offers a wide range of calculation methods that are also recognized by testing institutes:

  • Calculations according to data sheet DVS 705 and DVS 1612
  • Static strength verification, dynamic strength verification
  • Access to database for standardized profiles

Although stress determination is not part of the calculation standards, it is available in MDESIGN. Stresses are determined according to the nominal stress concept for known cross-sections. Only the weld seam itself is considered, the calculation of the base material is only possible according to the FKM guideline in the calculation module "General component strength verification".

Riveted and soldering joints

In addition to bolted and welded joints, soldered and riveted joints are also suitable for special applications. Based on well-known technical literature, MDESIGN provides results for the soldered and riveted joints modules:

  • Number of rivets required
  • Required diameter
  • Required length of rivets
  • Load capacity
  • Tensions

Bonded joints

If it is necessary to combine components without metallic connections, bonding can be a constructive alternative.

Characteristic values for the adhesives to be used are required for the selection and calculation of the strength.

MDESIGN provides a database with more than 220 adhesives from numerous manufacturers. The advantages of low damage or weakening of the components to be joined can also be decisive for the shape of the joint.

The following forms of stress can be selected:

  • Torsional load according to VDI 2229
  • Shear load according to VDI 2229
  • Tensile load according to VDI 2229
  • Access to database for characteristic values of well-known adhesive manufacturers, e.g. E.Epple, Henkel Loctite, UHU, Weicon
