Abstract: A simplified calculation model for use in predicting life consumption of a component subjected to loads during operation may be generated. Accordingly, a first set of load input data resulting from a first set of load sessions during operation is received. At least one of stresses, strains and temperatures for a critical area of said component is calculated by a numerical calculation model. Life consumption of said component is predicted based on said at least one of the numerically calculated stresses, strains and temperatures. Said simplified calculation model is generated defining a relationship between load input data and predicted life consumption by: assigning a plurality of linear difference equations for said simplified calculation model, and calculating parameters of said plurality of linear difference equations based on said relationship between the first set of load input data and said numerically calculated predicted life consumption.

Abstract: An assembly of a support plate and an exit window foil for use in an electron beam generating device. The support plate is designed to reduce wrinkles in the foil. The foil is bonded to the support plate along a closed bonding line bounding an area in which the support plate is provided with a pattern of apertures and foil support portions alternately. When vacuum is created in the housing the pattern is adapted to form a topographical profile of the foil substantially absorbing any surplus foil. Another aspect involves a method in a filling machine for sterilizing a packaging material web.
