SDC Verifier implements:
• Individual Loads;
• Load Sets;
• Load Groups.
A lot of loads and
combinations should
be checked according to
standards.

Standards and Custom Checks
Fatigue check according to different methods and
standards;
Plate Buckling according to ABS and DNV standards;
Custom Checks (anything can be checked as long as the
formula is known);
Custom Checks Examples;
API RP 2A Tubular Joint Check;

Fatigue Check example
(mean stress correction)
For single stresses
Fatigue Allowable Stress Design (Goodman relation)
Combined
Allowable Stress depends on classification
Element Group 6 more
than 2 millions cycles
K4 welds example
Used by standards as DIN 15018, FEM 1.001, NEN 2018/2019 and FKM

Allowable Stress vs Kappa
Weld Class K3 - Green Weld Class K2 - Red
Utilization Factor (Smax/Sallow)
Notch group/Weld Class
Allowable Fatigue Stress depends on Weld Class and Kappa=Smin/Smax
