Abstract
In this paper, elasto-plastic stress analysis in laminated thermoplastic composite plates having an elliptic hole in the middle is examined by using finite element method. Composite plates consist of four orthotropic laminations and bonded symmetrically \([\theta^{0}/-\theta^{0}]\). Uniform loadings in vertical direction are applied to the selected composite plates. The loading and reinforcement angle are gradually increased from the yield point of the plate. The load steps increased as 0.0001 MPa at each iteration. Iteration numbers are chosen 25, 50, 75 and 100. A quarter of the plate is taken into consideration due to symmetry. Elasto-plastic stresses are obtained according to load steps and orientation angles.
Highlights
Thermoplastic composites have many advantages, such as a high specific stiffness and specific strength, increased impact resistance and improved fracture toughness began to increase their importance
Elasto-Plastic stresses are important in failure analysis of thermoplastic matrix laminated plates
Elasto-plastic stress values emerging in lower and upper laminations are identical in terms of absolute value
Summary
Thermoplastic composites have many advantages, such as a high specific stiffness and specific strength, increased impact resistance and improved fracture toughness began to increase their importance. Elasto-Plastic stresses are important in failure analysis of thermoplastic matrix laminated plates. Arslan and Çelik, [3,4] studied an elasto-plastic stress analysis in symmetric and antisymmetric wovenreinforced polyethylene thermoplastic matrix composite that using finite element method and first-order shear deformation theory for small deformations. Karakuzu et al [6], examined elasto-plastic stress analysis by finite element method in metal matrix plates having spiral dents on the sides. Karakuzu et al [7], researched of the elasto-plastic stress analysis and residual stresses in woven steel fiber reinforced thermoplatic laminated composite plates for transverse uniform loads. Sayman [8], researched elasto-plastic stress analysis under vertical forces in stainless steel woven fibers aluminum metal matrix laminated plates. The loading is increased by 0.0001 Mpa increments at each loading step and iteration numbers are chosen as 25, 50, 75, 100
