| چکیده مقاله: |
| In this paper, the low velocity impact response of composite plates is investigated using three new impact models for contact force estimation and their results are evaluated considering both classical and first order shear deformation theories. The boundary conditions are considered as simply supported and the behavior of the material is linear elastic. The mass of the impactor is considered to be large and therefore the impact response is categorized as quasi-static. Validation of these results is done by comparing with the analytical, numerical and experimental results and shows good agreement. Results show that the new multi-degree-of-freedom spring-mass system is more accurate for calculating the contact force rather than the improved two-degree-of-freedom spring-mass system and half-sine model, especially when using first-order shear deformation theory. Validation of these results is done by comparing with the analytical, numerical and experimental results and shows good agreement. Results show that the new multi-degree-of-freedom spring-mass system is more accurate for calculating the contact force rather than the improved two-degree-of-freedom spring-mass system and half-sine model, especially when using first-order shear deformation theory. |
