“…Finite element approach has been widely used in fretting and wear [10,11]. Finite element approach has shown it efficiency in composite also [12][13][14][15]. Fretting has the nature of dissipation and degradation which means that during fretting entropy is generated.…”

Fretting fatigue is a degrading process which is responsible for considerable amount of mechanical structure failure every year. In the present study, a finite element model is proposed to show the effect of a bending moment on a flat surface under fretting loading. The results show that the bending moment has a major effect on the friction stress distribution on the surface of the two solids under contact. Finite element analysis predicts an increased damage effect on the surface of solids when a load is applied as a pure moment. The results predict elevation in the relative slip between the surfaces after applying the bending moment.

“…Today are widely used multilayer composite shells of revolution with reinforcements in spiral under angle α to the generatrix. Generally, such shells are locally orthotropic, however their main anisotropy axes x',', r in this case no coincide with axes of global system of cylindrical coordinates x,, r. Many works are carried out on such structure behavior in static regime (Li, 2007;Arashmehr et al, 2013;Rahimi et al, 2013). Same, composite shells explosion tests-related experimental data are available in technical literature (Fedorenko et al, 2005;Batra & Hassan, 2007;Leblanc & Shukla, 2010).…”

In the present work, an elasto-plastic model is proposed for the numerical analysis of dynamic nonlinear behavior of composite thick shells with reinforcements in spirals subjected to impulsive loading. Wilkins algorithm was taken to analysis physical and geometrical nonlinearity of stress-strain state of elasto-plastic thick composite shells. This study is carried out on two types of cylindrical composite shells in different reinforcement winding angles and different magnitudes of impulse loads. By a calculation code in finite difference, first the influence of physical non linearity on the stress-strain state of cylindrical monolayer shell was established and then the relationship between residual strains and the winding angle of the symmetric reinforcements was investigated. Finally, the influence of the winding angle of the orthogonal reinforcements on the residual strains of a bilayer composite shell was analyzed numerically.

Composite shell structures have many applications in aerospace industry in which deal with various loading abundantly. In present paper Strain gauge instrument with rectangular rosette strain gauges were used to detect the maximum stress and strain distributions along the shell composite structure. Also a finite element analysis was done for validation of experimental results. The FEM software used was ANSYS14. Impact test, density measurement, and bending test were performed in order to detect physical and mechanical properties such as toughness, principal stresses, and density, of the three laminated composite shells. In addition, the results between experimental and ANSYS were compared. It was observed that an important discrepancy is found between theoretical and experimental results. It was also found a large difference in modulus of elasticity, toughness, and tensile strength for each composite material. These differences are tabulated in many tables in the last paper.
