This research aims to understand how local deformation affects the fatigue threshold in soft brittle materials.
Conducted microscopic measurements of deformation fields.
Analyzed the relationship between load magnitude and fatigue fracture.
Investigated the mechanistic origin of fatigue thresholds in selected materials.
Identified specific local deformation patterns that correlate with fatigue failure.
Established a clear threshold load value necessary for fracture under repeated stress.
Abstract
Fatigue fracture, whereby a material fails only under repeated loading cycles, depends strongly on load magnitude. In most materials, the applied load must exceed a threshold value - the fatigue...
