“…Other studies also included experimental approaches to measure and determine product durability at early design stages ( Devlukia and Davies, 1987 ). Fatigue, failure, and reliability have appeared in recent literature connected with data analytics, accelerated tests, and computer-aided design tools ( Burger et al., 2021 ; Hribersek et al., 2021 ; Mohammadian and Ait-Kadi, 2010 ; Munson et al., 2018 ; Stamminger et al., 2018 ; Su, 2010 ; Wei et al., 2012 , 2013 ).…”

“…This method is essential to estimate the product's lifetime during the design phase, as it allows improvements to be made, that is, the positive effects of changes in the design that can reduce the frequency of failures or completely eliminate any identified failure [24]. It also reduces the period between the product's planning and the time to launch it on the market.…”

“…In some cases, tests are carried out on several samples until all of them fail, which ends up consuming a lot of time, but also, tests can be carried out in a certain period or until a certain number of failures are reached. However, the most common way is to test samples operating in severe conditions continuously [24].…”

— Reliability is an essential item for the product development phase, as it is from estimated values are obtained about how the product will behave and, consequently, about modes of design flaws and weaknesses. In short, these responses are important to offer to the market high quality products, in addition to providing safety to the customer. In this work, a product was proposed where its design was based on research on how its shape should be and three different raw materials were chosen to be applied to the product and, with the simulation, it was possible to discover the weaknesses and points of improvement and which material best suited the proposed product.

“…Milena suggested that the accelerated test should represent reliability of a product as it was actually used, and we shall focus on actual product exposures in their life scenarios. S. Hossein and Daoud proposed practical approaches to conduct accelerated degradation testing on new and available used samples to characterize its failure time and reliability. Kang et al .…”

The traditional reliability demonstration testing based on statistical method requires a large number of samples and long testing time, failing to satisfy the demand for short cycle and low cost. This paper proposes a new accelerated approach for determining reliability target of each environment stress, accelerated test profile, and comprehensive acceleration factor for multi-failure mode product to conduct assembly level accelerated demonstration testing under multiple stresses and levels. By decomposing the product from four levels, namely function, structure, mechanism, and stress, the products' weaknesses can be identified. The main failure modes and sensitive environmental stresses are determined based on environmental profile and FMMEA. In this design, the reliability is apportioned to each actual environmental stress by AHP. And the SSI model is used to establish accelerated stress profile. The overall acceleration factor can be derived from the model of assembly level accelerated testing. Combined with a statistical plan, the accelerated reliability demonstration testing plan and test profile is built. A case example is presented to illustrate the effectiveness of the proposed approach.
