Abstract:The using of "technical materials" speeded up lately. Because of this, parts are being designed from plastic, which have to sustain extreme stresses. The proper definition of material qualities is expensive; despite in every phase of designing, we need it to be done perfectly. In every industrial section it is important to work with exact material qualities, especially areas where there are strict safety rules (in connection with the lifespan). In this work we will introduce how to design suitable fatigue stress for the plastic samples and how to define the fatigue qualities of the various materials of Rapid Prototyping. This information could be important to change damaged equipments and parts in the military. Due to this, we performed the design of fatigue tests to help the designers elaborate military, safety improvements and proper renewing technologies.

“…Plastics have great inner attenuation, but have bad thermal conductivity, so specimens exposed to fatigue stress will increase their heat even under 10 Hz frequencies, and their flexibility modulus is decreasing as well. [1] DMA examinations give -in addition to many other -exact results on specimen's critical temperature which can serious impact on their results of fatigue stress tests. (Figure 1) The characteristics of technical plastics are defined in the specialized literature as a fully flexible and liquid mixture during the Dynamic Mechanical Thermal Analysis (DMTA).…”

Alongside the using of "technical materials', the direct 3D printed different plastic also speeded up lately. Accordingly to this, it is often designed parts, which have to sustain extreme stress. The proper definition of material qualities is expensive; despite in every phase of designing, we need it to be done perfectly. In every industrial section, it is important to work with exact material characteristics, especially in fields where strict safety rules have to be kept (in connection with the lifespan) the design of fatigue tests of 3D printed polymer specimens. We planned the examinations on the way to avoid the critical temperature range shown by the DMA examinations' results in the bending point of the inner friction coming up in the local range. This information could be important for the Military to change the busted parts quickly and sound. That is the reason why we designed these examinations in this way, so, it could help for designers in the field of military, in development of security technology and improvement of recovery.

“…The design-relevant region for sfrp parts in steering systems is high cycle fatigue [2], between 6•10 4 and 5•10 6 load cycles. The design of these parts is frequently based on isotropic, linear elastic numeric calculations, although it is possible to take into account the nonlinear, elastoplastic and anisotropic material behavior for quasi-static simulations and for crash calculations.…”

Abstract. The paper presents a strain-based approach for the lifetime calculation of short fiber-reinforced plastics which takes into account the elastoplastic and anisotropic behavior of the material. For this, a coupled process-structure simulation is used. The advantages of the new approach are shown by comparison between a linear elastic and isotropic Finite Element (FE) analysis using conservative estimation of the lifetime [1]. Tests of a steering system component subjected to load cycles are the basis. The material used is a glass fiber-reinforced polyamide 66 (PA66 GF30).
