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 ...

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.

Non-Gaussian Analysis of Herbarium Specimen Damage to Optimize Specimen Collection Management
Knowledge Engineering and Data Science, 2022 Damage to specimen collections occurs in practically every herbarium across the world. Hence, some precautions must be taken, such as investigating the factors that cause specimen damage in their collections and evaluating their herbarium collection handling and usage policy.
