text: Resistance spot‐welded joints containing press‐hardened steels are
seen to exhibit a fracture mode called total dome failure, where the weld nugget
completely separates from one steel sheet along the weld nugget edge. The effect
of weld nugget shape and material property gradients is studied based on damage
mechanics modeling and experimental validation to shed light on the underlying
influencing factors. For a three‐steel‐sheet spot‐welded joint combining DP600
(1.5 mm)–CR1900T (1.0 mm)–CR1900T (1.0 mm), experiments under shear loading reveal
that fracture occurs in the DP600 sheet along the weld nugget edge. In subsequent
numerical simulation studies with damage mechanics models whose parameters are
independently calibrated for every involved material configuration, three variations
of the geometrical joint configuration are considered—an approximation of the
real joint, one variation with a steeper weld nugget shape, and one variation
with a less pronounced gradient between weld nugget material and heat‐affected
zone material properties. The results of the finite‐element simulations show that
a shallower weld nugget and a more pronounced material gradient lead to a faster
increase of plastic strain at the edge of the weld nugget and promote the occurrence
of total dome failure.
