The process of ductile fracture which occurs due to the accumulation, growth and combination of defects or cracks of material is called ductile damage. Failure in materials can be predicted, using damage mechanics and damage criteria. On the other hand, most of the materials depended to the manufacturing process, are formed in warm or hot conditions so that; the temperature also affects on the ...
sandwich panel with central core honeycomb aluminum as one of the main shielding structures because of their high strength-to-weight ratio and improved energy absorption capacity, has been attracted the attention of many researchers and practitioners in recent years. this paper initiates and presents a new type of central core honeycomb formed by hydroforming process. the study is augmented by ...
Purpose: of this paper: The paper presents some results of extensive investigation of steel seam-welded tubes forming process, by applying combined treatment of material narrowing and expansion. The objective of executed numerical FE and experimental investigations was to determine the optimal technology for production of tubular product at simple tools and at the standard forming processing ma...
