The conversion tool from plate local element coordinate system into the global coordinate system is implemented in version 4.0. Global Plate Stresses are especially important to see the origin of the load. For the pictures above the global x-direction is used to show the bending moment in the full ship, while the global y stress plot shows the local bending at the hull due to the upward pressure of the hydrostatic water.
Full integration in SDC Verifier makes these stresses directly available for plotting:
Normally plate stresses are calculated in the element coordinate system which shows the table below:
With the SDC Verifier global plate stress in combination with extreme tables the maximum stresses in every direction can be shown in 1 overview table:
With the report generation tools SDC Verifier offers these plots and tables can be made for every global stress direction and every section with ease:
SDC Verifier wants to thank Alexander Naatje of Femto Engineering for his help and support in implementing this new visualization tool.

The strength of tubular members and tubular joints according to ISO 19902 standard is implemented in version 4.0.
For checking of large (offshore) lattice structures according to ISO 19902 the joints and members need to be recognized in the standard FEA model:
SDC Verifier automatically recognizes the members (left) and the Joints (right):
The Standard contains the following checks: axial, bending, shear, hydrostatic, combined and overall.
It is very easy to check the strength of tubular members for a set of results using Load Group (Envelop) extreme table:
Verification of the tubular joints is performed by Joint Check. Fully automated recognition of connections with their geometrical parameters and brace classification (that depends on loading) significantly speeds up the verification process.
ISO 19902 is the new standard based upon the older API RP 2A standard which was already implemented in version 3.8.5. Besides the implementation of this new standard also the following improvements compared to version 3.8.5 are added:
