samendrukt

Samendrukt is a term used in mechanical loading discussions to denote the coordinated application of compressive forces across multiple points or components within a single assembly. The concept prioritizes uniform stress distribution and aims to minimize differential deformation that can occur under localized loading.

Origin and usage: The word combines Dutch samen ('together') and druk ('pressure'). It has appeared in Dutch-language engineering forums and some cross-disciplinary writings since the early 21st century, though it remains uncommon in mainstream English-language literature.

Definition and scope: Samendrukt describes either truly simultaneous loading or carefully phased loading designed to create near-equal pressures across a workpiece or system. It is discussed in contexts such as tablet presses, calendering of laminated composites, electrode calendering in batteries, and geotechnical testing with symmetric boundary conditions.

Examples: In tablet manufacturing, actuation is adjusted so all cavities experience simultaneous pressure, improving tablet uniformity. In geotechnics, a samendrukt approach uses symmetric loading to reduce bending moments and differential settlement.

Evaluation: Benefits include improved density uniformity, reduced warpage, and better surface finish; drawbacks include the need for precise timing, sensor feedback, and higher equipment complexity and cost. Some critics argue the term is jargon unless accompanied by explicit load-path analysis.

Notes: The term remains largely informal and industry-specific; readers should consult local glossaries or standards for precise definitions in a given field.
