Parametric shape optimization of biaxial tensile specimen [PDF]
PAMM, 2016 AbstractCommon cruciform specimen for biaxial tensile testing of sheet moulding compound, take damage and finally fail in uniaxially loaded areas. When using these specimen, an observation of damage initialization and failure in biaxially loaded areas is, therefore, not possible.

Damage and fracture of the optimized X0‐specimen [PDF]
PAMM, 2021 AbstractThe paper deals with numerical and experimental results of the gradient based optimized biaxial X0‐specimen. The original, engineering based design has been optimized under producibility restrictions for two different loading conditions to gain a distinct (high or low) stress triaxiality maintaining a sufficiently homogeneous distribution in ...
