The Collaborative Research Center 1153 is investigating an innovative process chain for the production of hybrid components. The hybrid workpieces are first joined and then formed by cross-wedge rolling. Pinion shafts were manufactured to investigate the behavior of the joining zone under increased complexity of the forming process. For this purpose, six types of workpieces produced by three types...... hiện toàn bộ
Mô hình hóa hiệu ứng tải ngược bao gồm tình trạng dừng lại của độ cứng và quá trình tái dẻo sớm Dịch bởi AI
International Journal of Material Forming - Tập 1 - Trang 145-148 - 2008
W. Kubli, A. Krasovskyy, M. Sester
Bài báo này đề cập đến hiệu ứng Bauschinger trong mô phỏng hình thành tấm kim loại. Một khái niệm về mô hình vật liệu mới được trình bày, có khả năng xử lý chính xác các hiện tượng tái dẻo sớm, sự làm mềm tạm thời và tình trạng dừng lại của độ cứng khi đảo chiều tải. Bên cạnh dữ liệu tiêu chuẩn thường được sử dụng cho các mô phỏng dựa trên độ cứng đồng nhất, mô hình này chỉ yêu cầu thêm bốn tham s...... hiện toàn bộ

Influence of Sheet Metal Pre-forming on Edge Crack Sensitivity using an AHSS Steel Grade
International Journal of Material Forming - Tập 15 - Trang 1-11 - 2022
M. Feistle, A. Kindsmüller, I. Pätzold, R. Golle, W. Volk
Especially in the automotive sector, high-strength sheet materials are processed in the manufacturing industry. These steels often show a pronounced sensitivity to edge cracks. Because of this, many edge crack testing methods for a wide variety of stress conditions have been developed to describe the edge crack sensitivity of a material. Only the hole expansion test according to ISO 16630 has been...... hiện toàn bộ

Simulation of the forming process for curved composite sandwich panels
International Journal of Material Forming - Tập 13 - Trang 967-980 - 2019
S. Chen, O. P. L. McGregor, A. Endruweit, L. T. Harper, N. A. Warrior
For affordable high-volume manufacture of sandwich panels with complex curvature and varying thickness, fabric skins and a core structure are simultaneously press-formed using a set of matched tools. A finite-element-based process simulation was developed, which takes into account shearing of the reinforcement skins, multi-axial deformation of the core structure, and friction at the interfaces.

Integrating 3D printing of polymer matrix composites and metal additive layer manufacturing: surface metallization of 3D printed composite panels through cold spray deposition of aluminium particles
International Journal of Material Forming - Tập 15 - Trang 1-17 - 2022
Alessia Serena Perna, Antonio Viscusi, Roberta Della Gatta, Antonello Astarita
The integration of metals and polymers in the same component to couple the best properties and advantages of both these classes of materials can be useful for engineering applications. In this scenario, the aim of this paper is to integrate additive manufacturing of composites with cold spray deposition of metal particles: in particular, 3D-printed carbon fibre-reinforced plastics (CFRP) panels we...... hiện toàn bộ
Dyna-Die: Towards Full Kinematic Incremental Forming
International Journal of Material Forming - Tập 1 - Trang 1163-1166 - 2008
V. Franzen, L. Kwiatkowski, G. Sebastiani, R. Shankar, A. E. Tekkaya, M. Kleiner
This article focuses on the realization of a simple and kinematic tool setup for incremental sheet metal forming. It allows achieving a similar geometrical accuracy like a full specific support, but minimizes the tool setup and increases the process flexibility at the same time. In incremental sheet metal forming different process variants are in use. The simplest one is the single point increment...... hiện toàn bộ
On the influence of kinematic hardening on plastic anisotropy in the context of finite strain plasticity
International Journal of Material Forming - Tập 4 - Trang 255-267 - 2011
Ivaylo N. Vladimirov, Michael P. Pietryga, Stefanie Reese
The paper discusses the application of a newly developed material model for finite anisotropic plasticity to the simulation of earing formation in cylindrical cup drawing. The model incorporates Hill-type plastic anisotropy, nonlinear kinematic and nonlinear isotropic hardening. The constitutive framework is derived in the context of continuum thermodynamics and represents a multiplicative formula...... hiện toàn bộ
