“…Taking this into account, the calculation of reliability function R(P, τ) included the evaluation of two components: the reliability R(DM) at the beginning of service and the reliability R(τ, σ) during operation-R(P, τ)=R(DM)ÂR(t, σ). The component R(DM) was estimated by means of a conventional "load-strength" model, assuming the Gaussian law for load and strength values of MCOPV [20]:…”

This chapter provides some aspects to probabilistic modelling in solving analytical problems of system engineering. The historically developed system of the formation of scientific bases of engineering calculations of characteristics of strength, stability, durability, reliability, survivability and safety is considered. The features of deterministic and probabilistic problems of evaluation of the characteristics of strength, stiffness, steadiness, durability and survivability are considered. Probabilistic problems of reliability, security, safety and risk assessment of engineering systems are formulated. Theoretical bases and methods of probabilistic modelling of engineering systems are stated. The main directions of solving the problems of ensuring security and safety according to the accident risk criteria are determined. The possibilities of probabilistic modelling methods in solving the problems of strength, reliability and safety of engineering systems are shown in practical examples.

“…In such applications, COPVs offer significant advantages over conventional all-metallic pressure vessels due to high specific strength and moduli of composites [1]. However, there are certain difficulties in design and the analysis of the structural behavior of a COPV associated with the anisotropic properties of fibrous composites, complicated ply lay-up and a variety of possible limit states of its constituents [2]. This requires the development of computational models reflecting all significant geometric and deformation characteristics of composites vessels.…”

Abstract. Due to their high weight efficiency, filament wound composite overwrapped pressure vessels (COPVs) are widely used in aerospace and satellite structures. However, there are certain difficulties in design and analyzing the structural behavior of COPVs, which require improved computational models. The aim of this study is to compare models developed for finite element analysis of a COPV subjected to internal pressure. Factors the models should take into account to ensure adequate representation of the structural features are formulated. Custom procedures integrated into a commercial package are used to generate 3D and axisymmetric models. The results of the stress analysis of a pressure vessel with a thin titanium liner overwrapped by a carbon/epoxy composite obtained with different computational models are compared.
