Abstract

Penyambungan bahan thermoplastic polypropilen dengan teknik Friction stir spot welding (FSSW) telah banyak dilakukan. Walaupun kekuatannya sudah mencukupi, masih dihasilkan keyhole dan bekas shoulder yang cukup besar karena penggunaan ukuran soulder dan pin besar. Penelitian ini menginvestigasi sambungan polypropilen dengan teknik FSSW menggunakan shoulder dan pin lebih kecil pada geometri shoulder yang berbeda. Penelitian di awali dengan pemotongan lembaran polypropylene dengan panjang 150mm, lebar 30mm dan tebal 5mm. Sambungan tumpang sesuai dengan standar EN 12814-2 digunakan dalam penyambungan ini. Proses penyambungan dilakukan pada kecepatan putar 985, 1660, 2350 rpm dengan dua jenis tool (shoulder angle 0o dan 5o). Sambungan diamati struktur makro, kekerasan dan kapastas beban tariknya. Hasil penelitian menunjukan bahwa semua sambungan memiliki kegagalan getas. Seiring bertambahnya sudut shoulder dan kecepatan putar tool, ukuran nugget dan welding zone meningkat, sehingga meningkatkan kapasitas beban tari mencapai 2116 N. Geometri tool 2 berpotensi untuk dapat diaplikasikan dalam sambungan FSSW. The joining of thermoplastic polypropylene material using the Friction stir spot welding (FSSW) technique has been developed. Although the strength is sufficient, it still produces a large keyhole and shoulder marks due to the use of a large shoulder and pin size. This research investigates polypropylene joint with the FSSW technique using smaller shoulders and pins on different shoulder geometries. The research began by cutting of polypropylene sheets into 150 mm long and 30 mm wide and 5 mm thick. Specimens according to EN 12814-2 were used in this welding joint. The welding process is carried out at rotational speeds of 985, 1660, 2350 rpm with two types of tools (shoulder angle of 0o and 5o). The welding joint was then observed for macrostructure, hardness, and tensile load-bearing capacity. The results showed that all welding joints had a brittle failure. The increasing of the shoulder angle and the rotational speed increase the nugget size and welding zone thickness resulting in a higher tensile load-bearing capacity which reaches up to 2116 N. The tool with the geometric being used has the potential to be applied in the FSSW joint.

Abstract

Sloof yang menghubungkan dua kolom selama ini diperhitungkan sebagai balok ikat (tie beam) agar kolom tidak bergeser. Sloof diasumsikan menggantung atau tidak bertumpu di atas tanah. Sehingga sloof murni sebagai pengikat antar dua kolom. Namun, kenyataan di lapangan sloof bertumpu di atas tanah atau di atas pasangan batu. Oleh karena itu sloof akan menerima beban vertikal dari bangunan. Desain sloof perlu diubah karena kondisi ini. Analisis dilakukan dengan menggunakan program SAP2000. Tanah dan pasangan batu dimodelkan sebagai spring dengan input parameter modulus reaksi tanah dasar (ks). Hasil analisis menunjukkan bahwa penurunan fondasi telapak pada kondisi sloof bertumpu di atas tanah atau di atas pasangan batu lebih kecil dibandingkan kondisi sloof menggantung. Selisih penurunan rata-rata sekitar 26%. Beda penurunan dan angular distortion antara dua kolom menjadi lebih kecil ketika sloof bertumpu di atas tanah atau di atas pasangan batu dibandingkan kondisi sloof menggantung. Momen lapangan yang bekerja pada sloof menggantung adalah positif sedangkan momen tumpuan adalah negatif. Sebaliknya, momen lapangan yang bekerja pada sloof bertumpu di atas tanah maupun di atas pasangan batu adalah negatif, sedangkan momen tumpuan adalah positif.Sloof connecting two columns has been calculated as a tie beam to keep them from moving apart. It was assumed as the hanging sloof or not rested on the ground. Hence it was purely as a tie between two columns. However, in the field, sloof is rested on the ground or the stone foundation. Therefore the sloof will receive the vertical load of the building. The sloof design need to be changed due to this condition. An analysis was conducted using SAP2000. The ground and the stone foundation were modeled as springs at which the modulus subgrade reaction (ks) was the input parameters. The results showed that the settlement of footing when the sloof resting on the ground or the stone foundation was smaller than the hanging sloof. The difference of the settlement was about 26% on average. Differential settlement and angular distortion between two column footings became smaller when the sloof was rested on the ground or the stone foundation compared to the hanging sloof. The field bending moment that occurred on the hanging sloof was positive, while the restraint moment was negative. In contrary, the field bending moment that occurred on the sloof rested on the ground or the stone foundation was negative, while the restraint moment was positive.

Abstract

Two-phase flow is used in many industries such as nuclear reactors, boilers, condensers, liquefactions of natural gas, etc. Two-phase flow is a flow in a pipe which has two states of fluid such as solid-liquid, liquid-gas, gas-solid. In a two-phase flow, there are three channels, namely vertical, horizontal and inclined channels. In the horizontal channel, the most widely found flow is the flow patterns of stratified flow, bubble flow, plug flow, stratified wavy flow, annular flow, and slug flow. Refer to the previous research above, the flow patterns were mostly obtained by using an experimental study. The advantage of using the simulation is the ability to predict the flow pattern and pressure gradient before doing the experimental study so it can be known earlier if it will have an insecure flow pattern, i.e. slug flow. This research was conducted to find the flow pattern and pressure gradient by using a Computational Fluid Dynamics (CFD) software, the Ansys Fluent 19.0 Student. The model which was used is the Volume of Fluid (VOF) with the fluid of air-water and glycerin (40%-70%). The length of the pipe was 200 mm, the inner diameter was 1.6 mm, and the length of the test section was 100 mm. Liquid superficial speeds (JL) of 0.033 m/s; 0.149 m/s; 0.232 m/s; 0.539 m/s; 0.7 m/s; 2.297 m/s and 4.935 m/s were used, while the air superficial speed (JG) was 9.62 m/s. The result of the simulation showed slug annular and churn flow patterns. Slug annular was formed at JL= 0.033 m/s; 0.149 m/s and 0.232 m/s with the glycerin content of 40% and 50%. Slug annular pattern was formed when the glycerin content was 60% and 70% with JL= 0.539 m/s. Viscosity affects the flow pattern, the higher the glycerin content, the higher the viscosity and the more fluid than air. The higher the JL and glycerin content, the higher the pressure gradient.
