Auskeilungsdrückens

Auskeilungsdrückens refers to a specific type of deformation process in materials science, primarily observed in certain metal alloys and polymers. It involves a localized, often wedge-shaped yielding and subsequent plastic deformation that occurs at specific points or regions within a material. This phenomenon is typically driven by concentrated stress fields, which can arise from geometric discontinuities, material imperfections, or applied external forces.

The term itself, of German origin, literally translates to "wedge-shaped pressing" or "yielding in wedges." It describes the characteristic visual appearance of the deformation zone, where material is pushed or forced outwards in a triangular or wedge-like manner. This localized yielding can precede more widespread plastic deformation or fracture, and its presence can significantly influence the overall mechanical behavior and structural integrity of the material.

Understanding Auskeilungsdrückens is crucial for predicting material failure and designing components that can withstand specific loading conditions. Factors such as material properties, stress concentration levels, and environmental conditions can all play a role in whether and where Auskeilungsdrückens occurs. Research in this area often involves advanced experimental techniques, such as microscopy and digital image correlation, to analyze the deformation mechanisms and their progression.
