“…However, the dependence of the target on every component rises. Sometimes only a component failure can lead to the complete strike of the target [1,2]. Consequently, the most efficient path to destroy the target is the high-density regional damage [3,4].…”

By analyzing the fragmentation distributions of a cylindrical structure and a specific structure, the necessity of parallel control to the fragments is presented. The shell shape of structures has an influence on the fragment spatial distribution. A new design method for the shell shape is proposed. To facilitate the establishment of the numerical model and the machining for relative experiments, the mathematical description of the theoretical calculated generatrix of the shell is simplified. The fragment spraying processes of the designed structures are simulated, and end effects are analyzed. Based on the theoretical design and plentiful simulation data, the relationships between the size of the parallel fragmentation structure and the optimized curvature radius of the shell are expressed by an equation. The equation is validated by numerical means and can be a reliable reference to the design of the parallel fragmentation structure.

“…In equation 3, the process of obtaining P K/H starts with identifying the critical components by damage modes and effects analysis. 1,14,15 The fault tree analysis is introduced to illustrate the component redundancy. The shotline method is performed to simulate the interaction of the projectile and aircraft, and the information of each projectile's shotline through the aircraft is recorded including component location, thickness, and shotline obliquity angle.…”

In the combat environment, wing damage is of particular concern since the wing is the main component to generate lift which affects survivability or safety. Previous research has been mainly concentrated on the aerodynamic behavior of the aircraft with wing damage. However, the military analysts are more concerned about the specific value of survivability (measured by survival probability) so as to correctly plan combat operations. This paper proposes a method for quantitatively describing the relationship of aircraft survivability and damage holes with different sizes and different locations on the wing. Examples show that the survivability decreases with increasing hole size; the magnitude of survivability decrement reduces when moving the damage backwards or moving the damage toward the wing tip; when the effect of damage on the vulnerability is considered for different hole sizes, the survivability is reduced more significantly compared with the cases where the vulnerability is kept constant for all scenarios.

Referring to CATIA's 'assemblies + parts' modeling method, CATIA-based BIM (Building Information Modeling) technology has been proposed for highway tunnel design in this paper. A tunnel BIM is created by CATIA, which is based on a real case in China, focusing on the following 3 aspects: (1) Creating tunnel bolts by UDF + Loop cyclic arrangement method; (2) Using Sketch Tracer module to create tunnel portal; (3) Parameter is used to create and call the Catalog database. Then, bolt collision inspection and U-shaped groove concrete statistics are conducted with the help of the tunnel BIM created. Finally, the finite element analysis of tunnel construction process is carried out through the CATIA-Midas interface. The results demonstrate that the CATIAbased BIM technology can well adapt to the characteristics of tunnel and have well potential applications in tunnel design.
