The dynamic response of doubly curved shell under effect of environment sustainable temperature

The current work aimed to demonstrate the reliability of some engineering applications to work under hard conditions and thermal environment, which results in the failure of many engineering structures such as spacecraft components and to benefit from those results in order to achieve the required limits for sustainable development and reach the best results under the influence of those environments. according to extremely high specific stiffness and strength, composite laminates with fiber reinforcement were widely being employed in weight sensitively applications like aeroplanes and spacecraft which are under the influence of transient rectangular and sine pressure pulse loads during launch and in the orbit which consider the highest in the structure. In some situations, a thermo-mechanical transient loads become the dominant loads, and that one of the factors that can influence on the laminate design is their thermal stability. The present work presents a semi-analytical approach (levy-type) by using Matlab 2020 code to examine the effect of fiber orientation on the transient response such as the central deflection as well as normal stress response analysis of doubly curved composite shallow shell exposed to triangular and sinusoidal distributed pressure pulse loading. The results show that various materials, geometric characteristics, boundary conditions and temperature effect have different influences on response parameters.
