Abstract
  In this research, by improving the accuracy of existing high-order theories, a new corrected high-order composite cylindrical shell theory with twelve displacement components has been developed. In this theory, the effect of terms related to the trapezoidal shape of the shell cross-section (1+z/R) in ...  Read More

Abstract
  Microgravity and cosmic radiation are the space environmental stresses which can cause DNA damage in living organisms. Radiations injurie the cell DNA directly through the interaction of charged particles with DNA molecules or indirectly by the production of free radicals. In addition, radiation can ...  Read More

Abstract
  One of the leading challenges in the fabrication of natural fiber composites is the adhesion of the fibers to the matrix. Since improving the adhesion between the fibers and the matrix changes the mechanical properties of natural composites, fiber surface modification has been considered. In this study, ...  Read More
