Probabilistic Approach to Damage Tolerance Design of Aircraft Composite Structures

Multiscale Approach to Damage Analysis of Laminated Composite Structures

The presented work depicts results of a two-scale approach to the problem of damage and failure prediction on laminated composite structures. Modeling on the micro-level has enabled insight into the underlying physical processes which lead to homogenized properties of the macro-scale material. In this work, micromechanical analysis has been performed by application of the High Fidelity Generali...

Damage tolerance and residual strength of composite sandwich structures

A New Approach to Buckling Analysis of Lattice Composite Structures

Buckling strength of composite latticed cylindrical shells is one of the important parameters for studying the failure of these structures. In this paper, new governing differential equations are derived for latticed cylindrical shells and their critical buckling axial loads. The nested structure under compressive axial buckling load was analyzed. Finite Element Method (FEM) was applied to mode...

Impact Damage Management of Composite Laminated Structures by a Probabilistic Approach

A numerical procedure for the design of impact damage resistant composite laminated structures is proposed in the present paper. This procedure, based on probabilistic analyses, is able to support the design of complex composite laminated structures by accounting for the scatter in composite materials’ mechanical properties (related to the mutable environmental conditions experienced by an airc...

Probabilistic approach to the design of symmetric protein quaternary structures.

Probabilistic methods have been developed that estimate the site-specific probabilities of the amino acids in sequences likely to fold to a particular target structure, and such information can be used to guide the de novo design of proteins and to probe sequence variability. An extension of these methods for the design of symmetric homo-oligomeric quaternary structures is presented. The theory...
