In this work, the mechanical behavior of AZ31B-F magnesium alloy under cyclic loading is analyzed with goal contributing to advancement its use in design components and structures. To achieve goal, an experimental program was implemented evaluate response specific proportional loads different stress amplitude ratios. Afterwards, regression methods were applied extend data a wide range loads. As...

The development of additive manufactured metals is in the transition phase, from research into technology 3D printing and resulting properties towards their use industrial practice. article analyses possibilities producing bicycle frames using printing. stresses a frame are analysed for measured load spectra FEM simulation. approach to fatigue life assessment based on directly multipliers detai...

The goal of the present paper is to apply a multiaxial fatigue criterion, formulated in frequency-domain, welded components. In particular, proposed procedure requires (i) evaluate stress field at so-called hotspot and (ii) compute damage. A case study, represented by fillet-welded tubular T-joints under random loading, examined assess validity above estimating crack nucleation position. Finall...

Based on a previously published Through Process Modeling (TPM) for multiaxial fatigue life assessment of injection-molded components, this work aimed to capture the difference fiber orientation distribution ahead notch tips in flat notched samples PA6GF30 tested tension at ambient temperature. The originated from different locations injection gate an unchanged macroscopic geometry. Good lifetim...

The goal of the present paper is to discuss accuracy and reliability a procedure for fatigue strength estimation defective metals by considering some experimental data available in literature. In particular, behaviour three ductile cast irons (DCIs) containing solidification defects (i.e., micro-shrinkage porosity) simulated through above procedure, based on joined application area-parameter mo...
