The application discloses a random digital anti-fake image generation and application method, which comprises the following steps: 1) acquiring an infinite non-cyclic number; 2) determining the size of a digital anti-fake image; 3) extracting W*H numbers from the infinite non-cyclic number calculated in step 1); 4) generating a two-dimensional initial random image based on the extracted W*H numbers; 5) performing reinforcement processing on the initial random image to obtain an optimized random image; and 6) associating and combining the optimized random image with a specified two-dimensional code or bar code to generate an anti-fake code with high randomness and uniqueness. The application utilizes the digital distribution randomness of the infinite non-cyclic number to form a two-dimensional image, and then performs corresponding feature enhancement processing, so that the two-dimensional image becomes an anti-fake digital image with randomness, uniqueness, difficulty in replication and easiness in identification.

The invention relates to a method for manufacturing a component (1) made of a composite material, comprising one or more layers (2, 3) associated with one another. The method involves a series of steps (4) for the fatigue design of the component (1), comprising: (A) a first step of generating a discretized model (5), for example by means of a finite element model of the component (1), in which at least a first layer (2) and, as needed, at least a second layer (3) are divided into two or more first portions (6) and two or more second portions (7), respectively; (B) a second step of defining positions of one or more first injury initiation sites (8) and one or more second injury initiation sites (9) within each of the two or more first portions (6) and each of the two or more second portions (7), respectively; (C) a third step of assigning a fatigue strength parameter to each of the damage initiation sites; (D) a fourth step of establishing a load history to be simulated on the component on the basis of specific load conditions, the total number of cycles (NC) to be simulated being divided into discrete cycle blocks, each of which is assigned a load condition.
