Rainflow Counting Tool

Introduction Rainflow Counting method is used to determine the number of fatigue cycles that is based on a load-time history. It is used in the analysis of fatigue data in order to reduce a spectrum of varying stresses into a set of simple stress reversals. This simplification allows the number […]

Weld Stresses

Welded Connections (and weld stress in them) are crucially important for safety and durability of steel structures.  Here we will show a theory and FEA approach for weld stress calculation Introduction Welding – is a fabrication process, that joins materials (usually metals) through the high heating. This is one of the […]
