Additive Manufacturing represents a promising technology as an alternative to the conventional manufacturing process, with rapid and economic product development, well significant weight reduction freeform design. Although mechanical properties of additively manufactured metals, such Ti-6Al-4V alloy, are well-established, complete understanding fatigue performance is still pending aspiration due its inherent stochastic complexity influence several factors. This paper presents study speed...
Time and temperature, besides pressure in a lesser extent, represent the most significant variables influencing rheological behavior of viscoelastic materials. These magnitudes are each other related through well-known Time-Temperature Superposition (TTS) principle, which allows master curve referred to relaxation (or creep) be derived as material characteristic. In this work, novel conversion law interrelate curves at different temperatures is proposed by assuming they represented...
This paper presents a novel methodology to characterize viscoelastic materials, allowing the limitations of current conventional models based on Time-Temperature-Superposition (TTS) principle be avoided. It implies definition temperature-time field, T-t, from short-term recorded relaxation curves at different temperatures by establishing compatibility condition between temperature dependent modulus given time, E(T; t), and time for temperature, E(t; T). The solution resulting functional...
Abstract The fracture assessment of notched components based on cracked approaches leads to over‐conservative failure predictions. In the research literature, several are proposed overcome this problem using an apparent toughness, . Nevertheless, most these deterministic assumptions despite large and variable scatter exhibited by for different notch radii ( ρ ) or temperatures T ). This paper proposes a methodology deriving probabilistic field including effect temperature components. First,...
Abstract In this paper, the generalized local model (GLM) is applied to derive primary failure cumulative distribution function (PFCDF) of annealed glass in order achieve prediction structural glass. The uniqueness characterization demonstrated irrespective test, specimen size, and geometry used. Consequently, strength unequivocally derived a probabilistic way as material property, so that definition normalized testing specimens international standards might be put under question....
This work presents a probabilistic model to evaluate the strength results obtained from an experimental characterisation program on notched components. The generalised local method (GLM) is applied derivation of primary failure cumulative distribution function (PFCDF) as material property (i.e., independent test type, load conditions and specimen geometry selected for campaign), which guarantees transferability in component design. To illustrate applicability GLM methodology, performed using...
Many design scenarios of components made polymer materials are concerned with notches as representative constructive details. The failure hazard assessment these using models based on the assumption cracked leads to over-conservative estimations. Among different alternative approaches proposed that apparent fracture toughness, KcN is considered. In so doing, current deterministic underlying concept must be replaced by a probabilistic one take into account variability observed in results...
Due to the brittle nature of glass, study response glass elements subjected dynamics loadings is great interest, mainly when human injury resulting from breakage may occur. Laminated consists two or more layers monolithic and one viscoelastic interlayers. In this paper, a technique predict dynamic (deflections stresses) laminated using linear elastic model proposed validated. first step, modal parameters are calculated superposition technique. Then, coordinates element estimated equations...
Information and Communication Technologies (ICTs) have been increasingly applied to teaching. Although these tools improve reinforce the student's learning, students are not usually involved in creation of new digital material, but rather they only users them. This paper presents a methodology that combines collaborative learning with use ICTs, particular YouTube. The main objective is put as real protagonists process, reach deep wide range transversal competencies such teamwork, oral...
L-36 STOCHASTIC STRUCTURAL MODELING IN HAVANA L. HOLDEN 1 B. F. NIELSEN A. VAZQUEZ and C. TOWNSEND 2 Summary The Havana program can be used to model both large faults that are visible on seismic images small for which there is only indirect evidence. Each fault modeled individually using complex flexible models the simpler faults. Not geometry of plane but also actual rock movement deformation causing fault. This latter property
