Fibre Orientation at Notches and Fatigue Behaviour of Short Fibre Reinforced Polyamide
Fatigue strength of injection moulded short fibre reinforced polymer components depends upon fibre orientation with reference to the acting stresses. For the case of a short glass fibre reinforced (SGFR) polyamide 6, this dependence was expressed through a relationship derived from the Tsai-Hill criterion [1], with the strong assumption that fibres were parallel to each other. This relationship...
متن کاملFatigue behaviour of short fibre reinforced polyamide: morphological and numerical analysis of fibre orientation effects
The fatigue behaviour of injection moulded short fibre reinforced polymers depends upon fibre orientation, as shown in experiments conducted with notched specimens injected through different injection gates. The different fatigue behaviour is related to the different local elastic properties, as determined by the different fibre orientation patterns, resulting into different strain distribution...
متن کاملExperimental Identification of Fatigue Damage Model for Short Glass Fibre Reinforced Thermoplastic Composites
A polycyclic fatigue damage model for short glass fibre reinforced thermoplastics is developed and implemented into ABAQUS FE code using UMAT subroutine. The MNL model is introduced here in terms of damage rates: ( ) ) ( 2 0 1 2 0 2 1 2 1 1 ) ( ) ( N ij ij ij ij ij ij ij ij ij ij ij e E E N d d λ β ε γ ε β β α − − + + = ∂ ∂ = & (1) Where N is the number of cycles. αij, β...
متن کاملPrediction of Fatigue Life in Notched Specimens Using Multiaxial Fatigue Criteria
In this research, the effects of notch shape on the fatigue strength of 2024-T3 aluminum alloy notched specimens have been studied using experimental and multiaxial fatigue analysis. For this purpose, four set of specimens with different notch shape were prepared and then fatigue tests were carried out at various cyclic longitudinal load levels. Load controlled fatigue tests of mentioned specim...
متن کاملFatigue analysis of glass fiber reinforced composites
Some structure materials can match the flexibility and effectiveness of glass fiber Reinforced plastic, commonly called GFRP for short or simply fiberglass. Even it is very high strength, light weight, strong, and completely waterproof, it can be molded into free form shapes such as aerospace structures, and then also it has its endurance limits. Endurance limit means loss of strength and stiff...
