“…Table 3 presents the Young's modulus and Poisson's ratio of the materials defined in the FE model. The yield strength of the aluminum was defined as 150 MPa, and the stress‐plastic strain relation of the aluminum is adopted from the fitted relationship recommended by Barsoum et al., 36 as shown in Figure 18. The contact between different components was considered in this model.…”

This paper investigates the seismic behavior of a glass curtain wall system under various loading scenarios. Experimental set‐ups and approaches were developed to test full‐scale fully tempered (FT) insulating glass curtain wall systems subjected to three loading protocols: quasi‐static in‐plane loading, dynamic in‐plane loading, and dynamic coupled in‐plane and out‐of‐plane loading. A refined finite element (FE) model was developed to understand the behavior of the system. The average drift associated with glass cracking and fallout was found to be nearly identical for quasi‐static and dynamic in‐plane loading, indicating that in‐plane floor accelerations exerted marginal influence on the failure of the glass curtain walls. Bi‐directional loading led to an approximately 30% decrease in the glass fallout drift compared with in‐plane loading. This is because the out‐of‐plane drift placed an increased stress demand on the glass panel, as indicated by the FE analysis. Both the experimental tests and FE analysis revealed that the ASCE 7–16 formula, which is used to calculate the drift of contact between the glass and frame, is nonconservative as it does not consider the deformation of the surrounding frame and the friction between the gasket and the glass. The failure mechanism of the glass panel was caused by the stress concentrations at the diagonal corners due to glass‐to‐frame contact. The FE analysis indicated that the interactional effect among different glass units was negligible, and the glass panels exhibited a similar stress state regardless of their positions.

“…Material aluminium alloy adalah sejenis logam metal, yang dapat didaur ulang kembali maupun dapat diproduksi ulang (Ho et al 2020). Kekuatan pada Aluminium Alloy lebih kecil dari bahan baja namun memiliki berat yang lebih ringan dibandingkan dengan bahan besi dan juga Aluminium Alloy tahan terhadap korosi sehingga lebih banyak digunakan di kendaraan atau industri otomotif (Ho et al 2020); (Barsoum et al 2014). Setelah melakukan pemilihan material yang akan digunakan pada penelitian ini dilanjutkan dengan perancangan dan analisa.…”

Tools in the production process are needed in the production process in order to accelerate and improve the quality of production, especially in the automotive industry. In this study, a jig positioning machine design will be designed which is used when assembly on the roof panel of a car so that it can help areas that are difficult to reach when doing assembly or design on the roof panel of the car. After designing the required design for the car interior roof panel assembly, it is necessary to test the design of the machine so that when the material on the machine ready to be made is already in the safe category. Testing on the machine is carried out using a material with the type of Aluminum Alloy 6035-t5 with the addition of different force factors, namely 34.3N, 39.2N, and 44.1N. The addition of the force factor is based on the maximum load given when doing the roof panel assembly on the car. The test is carried out by performing simulations using CAD Software on the arm of the jig positioning machine which will be the support when applying the load. The simulation carried out will analyze the value of material suitability factors including the value of deformation, strain-stress, and factor of safety on the jig positioning machine. The results of the simulation show that there is a change in the value of the material suitability factor due to the difference in the applied force. The suitability factor of the material on the designed jig positioning arm can accommodate the weight of the load with a maximum force of 44.1N with a maximum displacement value of 1.062e+02 mm, a stress value of 1.087e+08N/m^2, a FOS value of 1.33e+00, and a Strain value of 1 ,19e-03. Based on the simulation results of the suitability factor of the material, the jig positioning arm is within safe limits.

A B S T R A C T In this study, the fatigue strength of inclined butt welds subjected to a proportional multiaxial stress state generated by uniaxial loading is studied in nominal and local stress concepts. The local methodologies studied included principal stress hypothesis, von Mises stress hypothesis and modified Wöhler curve method. Nominal methodologies included modified Gough-Pollard interaction equation, the design equation in Eurocode3 and the interaction equation in DNV standard. Results are evaluated along with data published in relevant literature. It is observed that both local and nominal stress assessment methods are able to estimate multiaxial fatigue strength. No obvious difference in fatigue strength is observed in the nominal stress concept, but the notch stress concept is able to capture a decrease in fatigue strength in shear-dominated joints. It is concluded that modified Wöhler curve method is a suitable tool for the evaluation of fatigue strength in joints dominated by both normal and shear stresses.Keywords fatigue strength; multiaxial stress ratio; multiaxial stress state; welded joints; weld inclination.N O M E N C L A T U R E FAT 95% = Fatigue strength corresponding to 2 × 10 6 cycles at failure with a survival probability of 95% and a confidence level of 75% FAT 50% = Fatigue strength corresponding to 2 × 10 6 cycles at failure with a survival probability of 50% and a confidence level of 75% E s = Elongation specified E = Young's modulus NA = Not applicable N f = Number of cycles to failure R = Stress ratio R y = Ratio of minimum yield to ultimate tensile strength of the material CV = Comparison value dependent on type of loading and material T = Triaxiality F = Applied load A = Weld throat area a = Weld throat size l = Weld length L = Length of flat plates t = Thickness of plates w = Specimen width w = Damage state variable f wd = Weld metal ultimate tensile strength k = Slope of SN curve k o = Slope of design SN curve Correspondence: M.
