Abstract: The production technology of silt sintered porous brick in Nantong has been introduced from the following three aspects: the first one, the excavating and processing of raw materials, the second one, the preparation and amount of inside fuel; the third one, mix design and the optimization design of hole shape structure. Four mix schemes have been designed. According to the new standard requirement, using staggered arrangement article rectangle holes and rectangular hole, designed a structure which was eight 36mm*13mm rectangle holes, fifteen 21mm*13mm rectangle holes and the hole rate was 28.4%.

Abstract: One of the needs of modern sheet metal forming is reliable knowledge about the formability of a given material. In sheet metal forming formability is usually related to the ability to have high values of the strain until failure, where this failure can be local necking and/or fracture. This high values of strain is called limiting strain which is not only influenced by material but also by the geometric features of sheet material. In this work, influence of hole shape and the patterns in which holes are arranged on limiting strain, are studied using experimental and numerical techniques. Both experimental and numerical analysis reveals the same.
