Due to high strength to weight ratio and high specific modulus, laminated composite plates are
different applications, the skew laminated composite plate are widely used in these applications. Therefore, the
free vibration behavior of skew composite plate analysis is one of the most important behavior and it is the main
purpose of several studies. In this work, two finite element models were built to simulate the skew composite
plates using ANSYS APDL version (17.2). The first model was the 2-D models based on SHELL281 while the
second model was 3-D models based on SOLID186. The two models were used to study the effects of skew angle,
width-to-length ratio, fiber orientation, supporting type and layers layout on the fundamental frequency of
laminated skew plates. The skew angle was varied from (0o) to (75o) while the fiber orientation was varied from
(0o) to (90o) and the width-to-length ratio was (0.5,1,1.25, 1.5 and 2). (SSSS), (SFSF) and (FSFS) types of
supporting were selected and three types of layers layouts were used. The results showed that skew angle and
width-to-length ratio fundamental frequency are strongly and separately effect on the fundamental frequency.
While the fiber orientation, supporting type and layers layouts have a slight effect on the fundamental frequency.
Finally, the combination effects of the five parameters gave a different variation form in the fundamental
frequency of the laminated skew plates.
