In research, composite parts adhesively joined with single-lap joint (SLJ) and intermediated material under tensile load were examined by finite element analysis (FEA). While T700 Carbon/epoxy was used for composite parts and intermediate material, DP 410 type was preferred for adhesive. The numerical studies were carried out by ANSYS 14.5 based on finite elements method. The von-Mises failure criteria and the Tsai-wu failure criteria were respectively considered for adhesive and composites. The analyses were firstly actualized to determine the failure loads for each parameter situation. The stresses at obtained failure load for each parameter state were investigated. The critical equivalent stresses on adhesive layers were examined and the critical stress lines for length and width was determined. The distributions of normal and shear stresses in all directions were obtained by considering critical stress line on adhesive layers. Similarly, the von-Mises stress distributions were obtained. Considering critical stress lines, the stress distributions on width and length of overlap dimensional were compared. The effects of overlap dimensional, orientation angle and intermediated material on effect of joint zone were investigated.

In this study, Multiwall carbon nanotubes (MWCNT) were used as a reinforcement element in the hybrid composites of ZA27-Al2O3 produced by powder metallurgy routine. In the samples, the MWCNT were chosen as 1, 3, and 5 % respectively. By using planetary ball milling, the samples were produced in 4 hours with 10-diameter steel balls, and then the powders were pressed with a 20-ton capacity manual press machine after sintering at 400 °C. The microstructures of the composites were examined by optical microscope and their densities were measured with the principle of Archimedes. Furthermore, the mechanical properties were examined by applying the Vickers hardness test. The result indicates that the addition of MWCNT leads to increase in hardness values. The maximum hardness scale value is observed in the sample of ZA27-Al2O3-5% MWCNT.

Cylindrical panels are one of the most essential structural members of engineering structures, with mechanical, civil, aeronautical, and marine engineering applications. They are subjected to a wide range of vibrational loads. This article presents a novel higher-order porosity distribution and a free vibration analysis for porous orthotropic cylindrical panels resting on elastic foundations under higher-order shear deformation theory. It is assumed that cylindrical panels are composed of porous materials with uniformly and non-uniformly distributed pores. The porous panels' material properties are distributed in the thickness direction using specific functions. The equations of motion are derived using Hamilton's principle based on trigonometrical shear deformation theory and solved by performing the Galerkin solution procedure with simply supported edge conditions. The accuracy of the obtained natural frequency equation is confirmed by comparing the results to those of previously published in literature. Under comprehensive parametric studies, the influence of porosity coefficient, porosity distribution patterns, radius-to-curve length ratio, orthotropy, and stiffness of elastic foundation parameters on the free vibration response of porous orthotropic cylindrical panels are discussed in detail.

Concrete structures may be subjected to dynamic loadings like earthquakes, impact, and vehicular loads. These loads may cause considerable damage to infrastructures and shorten their life span. To reduce the effects, improving concrete’s dynamic properties is important. This can be done using granular elastic components and fibers in the production of concrete. This research explores the influence of using coated aggregates on the physical, mechanical, and dynamic properties of concrete. Experimental investigation on concrete with epoxy, epoxy-sand, and epoxy-crumb rubber as a partial replacement of coarse aggregates at different volume fractions ranging from 5% to 20% was conducted. Furthermore, the dynamic modulus of elasticity of concrete with coated aggregate was determined by measuring the resonant frequencies of flexural vibrations in a prismatic beam using an impactor (hammer). Results indicate that partial replacement of epoxy-crumb rubber coated aggregates in concrete shows a reduction in mechanical proprieties. However, significant improvements in the mechanical and dynamic properties of concrete were observed by the partial replacement of coarse aggregates with epoxy and epoxy-sand coated aggregates. Compressive strength and dynamic elastic modulus were enhanced by 12% and 10%, respectively, when concrete with 15% epoxy-sand coated was used. The results showed that concrete specimens using epoxy and epoxy-sand coated as a partial replacement for coarse aggregate have higher mechanical properties as compared to those of concrete specimens with epoxy-crumb rubber-coated aggregates. Moreover, the results showed that the calculated values of the dynamic modulus of concrete using the empirical relations proposed by Popovics and Hansen were overestimated as compared to the experimental values.

Prior to casting of concrete, proper supervision and attention to camber provision in bridge construction are required. It is also critical to use an appropriate quality control manual, pay due attention to reinforcement bar placement, and have a high level of formwork design before construction begins. If these issues are not properly addressed, performance of structures will be affected. In this research, performance of a 40.5m box-girder reinforced concrete bridge which was constructed without having proper camber is studied. As camber was the most important issue of the bridge under investigation, the impact on strength and serviceability requirements is compared to the standard. A dynamic load test with an Arduino type accelerometer is performed to assess the bridge's current condition in relation to the serviceability limit requirement. The deterioration of reinforced concrete (RC) sections due to reinforcement corrosion, creep, and an increase in load intensity, as well as the corresponding statistical distributions are considered to estimate the long-term effect of bridge deflection. The time-variant analysis results show that a linear decrease in deflection reliability indices with the bridge's expected service life of 58 years and strengthening it increased to 85 years.

Indonesia merupakan negara maritim yang memiliki wilayah perairan yang luas, salah satu upaya untuk melindungi bagian lambung kapal dari korosi adalah dengan menggunakan teknologi pelapisan. Pada penelitian ini dilakukan proses karakterisasi hasil image processing pada lambung kapal untuk mengetahui tingkat korosi pada lambung kapal. 4 proses tahapan, diantaranya: Pengambilan sampel dan citra gambar lapisan bagian-bagian kapal yang perlu di maintenence dan di-coating, Pada pembuatan prototype pengujian hasil coating dirangkaikan dengan menggunakan mini PCNVIDIA Jatson Nano dengan menggunakan webcam, kemudian citra gambar yang didapatkan akan diolah menggunakan deteksi tepi menggunakan cany untuk mendapatkan kontur dari penampang bilge dari kapal. Selanjutnya menggunakan Neuraal Network sebagai bahan tiruan untuk membuat citra yang tertangkap dari hasil capture prototype terhadap hasil coating atau pelapisan pada bagian-bagian kapal yang diamati. Hasil dari berbagai tangkapan citra diproses dan diamati bentuk, pola, kontur, korosi dan pelapisan yang terbentuk. Metode image processing dapat dilakukan sebagai salah satu metode inspeksi hasil coating dengan hasil pembacaan pada data dan software dengan 2 hasil pembacaan pada data yakni reject atau accept. Nilai gradien berkaitan dengan perubahan MSE, sehingga nilai gradien tidak dapat digunakan sebagai acuan untuk membenarkan performa model. Adanya pertambahan iterasi nilai neural network dan neural target yang dihasilkan bernilai linier.

Teknologi berkembang sangat pesat beberapa tahun terakhir terutama pada teknologi berbasis Radio Frequency Identification Device (RFID). Hal ini disebabkan oleh banyaknya kebutuhan yang menggunakan teknologi. Pemanfaatan sistem RFID di Indonesia sebagian besar masih menggunakan perangkat keras RFID seperti transponder RFID dan RFID reader module yang dibeli dari negara lain seperti Cina atau negeri lainnya. Industri di Indonesia yang menggunakan RFID juga rata-rata masih membeli dan tidak memproduksi sendiri. Dari masalah yang ada, maka adanya peluang untuk memproduksi perangkat RFID ini baik transponder RFID maupun modul pembaca transponder RFID yang mirip dengan RFID yang sudah ada. Dalam penelitian ini dilakukan pembuatan modul pembaca transponder RFID dengan tahapan yang dimulai dari membuat skematik rangkaian modul pembaca transponder RFID, membuat layout PCB, mencetak PCB sesuai desain PCB, melakukan assembly komponen dengan menggunakan solder manual, dan melakukan pengujian. Hasil pengujian fungsi menunjukkan bahwa modul pembaca transponder RFID yang dibuat hanya bisa membaca kartu RFID dengan jarak tapping maksimal pada jarak 7 mm, sedangkan modul pembaca transponder RFID yang di pasaran bisa membaca kartu RFID dengan jarak tapping bisa lebih dari 7 mm.
