TITLE

Reliability prediction of tensile strength of a glass fiber reinforced polyamide using response surface method

ABSTRACT

The present paper consists firstly in developing mathematical models to predict tensile strength of a glass fiber reinforced polyamide. Based on response surface method (RSM) a mathematical model has been determined, in which three factors with three levels are implemented. Glass fiber content, temperature and strain rate are chosen as the main input parameters in this study. The tensile strength is considered as output response which is evaluated through experimental tests. Secondly the reliability of tensile strength is proposed based on the developed mathematical models, where the dispersions of: (i) the Glass fiber content and (ii) the temperature are taken into account using the Strength Load method with the Monte Carlo simulation. The proposed approach can be used as a powerful and an interesting method for engineering design, to determine with more secure the tensile strength behavior of a glass fiber reinforced polyamide
