“…illustrated that for the pressure path with a specified maximum amount, the workpiece was formed adequately with minimum sheet thickness reduction. The consistency of the decisions built on the FEM basis is highly dependent on the attained degree of the physical parameters and numerical accuracy of the simulation [17][18][19][20][21][22]. Many researchers involved in this domain focused their efforts on improving both the quality of the theoretical models implemented in the simulation programs and the efficiency of their applied computational strategies [23,24].…”

Owing to the reduction of rupture instability and the avoidance of wrinkle defect, the hydrodynamic deep drawing (HDD) process is gradually becoming attractive for fabricating lightweight and complicated products. Meanwhile, since metallic materials present anisotropic deformation behavior, it is necessary to select an appropriate constitutive model for the prediction of plastic deformation behavior of applied material with high precision. In the present research, several anisotropic yield criteria, namely, Hill’48, Yld2000-2d, and BBC2005, were implemented to investigate the effects of yield functions on the prediction accuracy of the critical process window and deformation behavior for the HDD process of 2024 and 5754 aluminum alloys. Material constants in the yield criteria were determined by applying uniaxial and equi-biaxial tension tests and optimizing an error-function using the Levenberg–Marquardt algorithm. Furthermore, the process window diagram was computed utilizing the stress analytical model combined material properties with workpiece geometrical features. Numerical simulation results of predicted material anisotropic parameters, process window, and HDD deformation for aluminum alloys were compared with the experimental data. Through the comparison of diverse yield criteria based on materials’ anisotropic coefficients, critical process window prediction, earing profile, and thickness distribution, it was revealed that the Yld2000-2d and the BBC2005 yield criteria can offer more precise models of material behavior in planar anisotropy properties for the HDD process of 2024 and 5754 aluminum alloys.

ABSTRAKPedal Brake berfungsi sebagai tempat pijakan kaki pada sistem pengereman pada salah satu produk motor roda tiga di Indonesia. Pembuatan pedal brake menggunakan proses drawing yaitu proses dimana gaya diberikan pada benda kerja agar terdeformasi plastis mengikuti bentuk dari punch dengan kedalaman tertentu. Dalam pembuatan pedal brake menggunakan proses drawing terdapat potensi cacat yang bisa terjadi akibat besarnya gaya serta tingkat kedalaman cetakan. Analisa draw ability dilakukan untuk mengetahui seberapa besar kedalaman proses drawing sebelum benda kerja mengalami kegagalan dengan menghitung nilai Limiting Drawing Ratio (LDR) dan rata-rata plastic strain ratio (Ravg). Simulasi dilakukan untuk mengetahui parameter seperti gaya pembentukan, jumlah energi yang digunakan beserta potensi cacat yang timbul pada pedal brake seperti earing dan kegagalan pada saat melakukan proses drawing. Dari hasil perhitungan LDR sebesar 1,028 dan Ravg sebesar 2,8 untuk jenis material ST-37 menunjukkan bahwa kemampuan draw ability yang rendah dengan gaya pembentukan maksimum sebesar 92,8 kN dan energi yang diserap sebesar 0,69 kJ. Nilai Ravg sebesar 1,2 untuk jenis material ST-37 cukup besar sehingga potensi terjadinya earing tidak terlalu nampak untuk proses drawing. Perbandingan antara analisa teoritis dan simulasi memiliki error sebesar 6% sehingga hasil masih dapat dikatakan valid. Kata kunci: drawing, dies, earing, limmiting drawing ratio, rata-rata plastic strain ratio. ABSTRACT Brake pedal serves as a place of footrest on the braking system on one of the three-wheeled motorcycle products in Indonesia. Making the brake pedal using a drawing process is a process whereby the force is applied to the workpiece to be deformed plastic following the shape of the punch with a certain depth. In making brake pedals using the drawing process there are potential defects that can occur due to the size of the force and the depth of the mold. A draw ability analysis was done to find out how much depth of drawing process before work object failed by calculating the value of LimitingDrawing Ratio (LDR) and average plastic strain ratio (Ravg)

ÖZSonlu elemanlar analiz programlarında malzemenin elastik ve plastik davranışı doğru tanımlanırsa, sonuçların hata payı düşmektedir. Başarılı analiz sonuçları elde etmek için önemli parametrelerden birisi ise akma kriteri seçimidir. Literatürde geliştirilmiş birçok akma kriteri mevcut iken bazıları sonlu elemanlar analiz programlarına dahil edilmektedir. Bazı analiz programlarında bu kriterler tanımlıyken (model parametre değerleri girilerek), bazılarında da programa kod yazarak ilave edilmektedir. Bu çalışmada BBC2000, BBC2003, BBC2005, BBC2008 akma kriterlerinin iki farklı alüminyum alaşımındaki model tahminleri karşılaştırılmıştır. Aynı zamanda BBC2008 akma kriterinde parametre sayısının etkisi de incelenmiştir. Daha fazla parametreli modelin deney sonuçlarını daha iyi tahmin ettiği görülmüştür. ABSTRACTIf the elastic and plastic behavior of the material is correctly defined in the finite element analysis programs, the margin of error reduces. One of the important parameters to obtain successful analysis results is the yield criterion choice. While there are many yield criteria developed in the literature, some of them are included in finite element analysis programs. In some analysis programs while these criteria are defined (by entering the model parameter values) and some are added by writing code to the program. In this study, model estimates of BBC2000, BBC2003, BBC2005, BBC2008 yield criteria are compared in two different aluminum alloys. At the same time, the effect of the parameters number on the BBC2008 yield criterion is examined. It is seen that the more parameters model predicts better the experimental results.
