The delamination in curved composite laminates is one of the main defects, especially in
aerospace structures. To optimize the design of the delaminated composite panels under …

Auxetic materials are those that exhibit negative Poisson's ratios. Such a unique property
was shown to improve the indentation and impact resistances. Angle-ply composite …

Introducing auxeticity or negative Poisson's ratio is one potential solution to mitigate the low
velocity impact damage of fiber reinforced polymer matrix composites, which can be …

Microcrack formation and delamination growth are the main damage mechanisms in the
fatigue of composites. They lead to significant stiffness loss, introduce stress concentrations …

The mechanical response and damage sequence of composite materials are nowadays still
a topic of ongoing research. However, many parameters influencing their overall behavior …

One of the main methods for improving the strength of the notched laminates, which are
commonly used in the engineering structures, is to employ a stringer in a proper …

Presented test results on transverse cracking in cross-ply laminates upon tension–tension
cyclic loading show that the increase of crack density depends not only on the maximum …

The current study considers free vibration of the spherical panel with magnetorheological
(MR) fluids core and magneto-electro-elastic face sheets. The panel is subjected to electro …

An energy based evolution rule is developed to predict the propagation of mid and outer-ply
matrix cracks in laminates with the layups of [0 n/θ m] s and [θ m/0 n] s subject to tensile …

In the notched structures, to achieve maximum buckling resistance in comparison with
structural weight, the optimal design of a stiffener is very important. In this research, after a …
