Preface to the English Version of the 5th Edition. For engineers concerned with construction and calculation in mechanical engineering or in related fields of industry the FKM-Guideline for analytical strength assessment is available since 1994. This guideline was elaborated by an expert group "Strength of components" of the "Forschungskuratorium Maschinenbau (FKM), Frankfurt/Main," with financial support by the Bundesministerium fur Wirtschaft (BMWi), by the "Arbeitsgemeinschaft industrieller Forschungsvereinigungen 'Otto von Guericke" and by the "Forschungskuratorium Maschinenbau. Based on former TGL standards and on the former guideline VDI 2226, and referring to more recent sources it was developed to the current state of knowledge. The FKM-Guideline - is applicable in mechanical engineering and in related fields of industry, - allows the analytical strength assessment for rodshaped (lD), for shell-shaped (2D) and for block-shaped (3D) components under consideration of all rele
