Optimized Specimen for Paperboard Shear Delamination Testing
Background
The out-of-plane shear behavior of paperboards plays a critical role in converting processes such as creasing and folding. The recently proposed Split Double Cantilever Beam (SDCB) specimen has been used to characterize this behavior using a cohesive zone model, but its large size poses handling challenges.
Objective
This study aims to optimize the SDCB specimen configuration to improve manageability while maintaining the quality of experimental measurements.
Methods
A design of experiments (DOE) approach and finite element analysis incorporating a mixed-mode interface model were used to analyze the influence of key specimen parameters. Shear reaction force and rotation relative to shear deformation were assessed to guide the optimization.
Results
A redesigned SDCB specimen was identified, achieving a 40% reduction in size and weight (retaining 60% of the original dimensions) without compromising the experimental quality. The optimized configuration maintained comparable measurement accuracy to the original design.
Conclusions
The proposed SDCB specimen redesign offers a more manageable experimental setup, enhancing usability in experimental studies while preserving the reliability of shear behavior characterization.
期刊介绍：
Experimental Mechanics is the official journal of the Society for Experimental Mechanics that publishes papers in all areas of experimentation including its theoretical and computational analysis. The journal covers research in design and implementation of novel or improved experiments to characterize materials, structures and systems. Articles extending the frontiers of experimental mechanics at large and small scales are particularly welcome.
Coverage extends from research in solid and fluids mechanics to fields at the intersection of disciplines including physics, chemistry and biology. Development of new devices and technologies for metrology applications in a wide range of industrial sectors (e.g., manufacturing, high-performance materials, aerospace, information technology, medicine, energy and environmental technologies) is also covered.
