Motivation – Elastic contact deformations are critical factors influencing the mechanical performance, load distribution, and structural integrity of mechanical assemblies. Even the smallest geometrical deviations at contact surfaces, often introduced during manufacturing, can lead to localized stress concentrations, uneven load transfer, and ultimately a reduction in contact stiffness. These effects can significantly impact the reliability, durability, and functionality of assembled components. Understanding the influence of geometrical deviations on elastic contact behavior is essential for optimizing tolerance limits and ensuring robust product performance.

Therefore, this Master's thesis focuses on analyzing how random geometrical deviations impact elastic contact deformation and load distribution in mechanical assemblies. By understanding these effects, it can optimize tolerance limits, improve product reliability, and enhance manufacturing efficiency.
