Experimental and Finite Element Analysis on Rounded Corners Square Shape Tube Hydroforming Process [PDF]

Engineering and Technology Journal, 2014
Tube hydroforming is a forming process where an inner pressure combined with axial feeding deforms the tube to the shape of a die cavity, i.e. the process state where the hardening of the material is unable to resist the increase in inner pressure and ...

Hydroforming Process for an Ultrasmall Bending Radius Elbow

Advances in Materials Science and Engineering, Volume 2018, Issue 1, 2018., 2018
Bent pipes are widely used in automotive, aviation, and aerospace industries for delivering fluids. Parts having small relative bending radiuses are called elbows. However, fabricating a thin‐walled elbow part using the simple bending process poses many challenges. One possible way to manufacture elbows is with the stamping‐welding process.

Corrosion Behavior of Brazed Zinc‐Coated Structured Sheet Metal

International Journal of Corrosion, Volume 2017, Issue 1, 2017., 2017
Arc brazing has, in comparison to arc welding, the advantage of less heat input while joining galvanized sheet metals. The evaporation of zinc is reduced in the areas adjacent to the joint and improved corrosion protection is achieved. In the automotive industry, lightweight design is a key technology against the background of the weight and ...

Pneumatic Formwork Systems in Structural Engineering

Advances in Materials Science and Engineering, Volume 2016, Issue 1, 2016., 2016
Concrete as a construction material is characterized by high compressive strength, low tensile strength, and good casting ability. In order to fully utilize the potential of this material, the form of load‐carrying structures has to be designed according to the stress distribution in the structure.

Reliability Evaluation for the Running State of the Manufacturing System Based on Poor Information

Mathematical Problems in Engineering, Volume 2016, Issue 1, 2016., 2016
The output performance of the manufacturing system has a direct impact on the mechanical product quality. For guaranteeing product quality and production cost, many firms try to research the crucial issues on reliability of the manufacturing system with small sample data, to evaluate whether the manufacturing system is capable or not.

Inverse Approach to Evaluate the Tubular Material Parameters Using the Bulging Test

Advances in Materials Science and Engineering, Volume 2015, Issue 1, 2015., 2015
Tubular material parameters are required for both part manufactory process planning and finite element simulations. The bulging test is one of the most credible ways to detect the property parameters for tubular material. The inverse approach provides more effective access to the accurate material evaluation than with direct identifications.
