Numerical simulation of the loosening defect When the procedure of plastic processing is simulated, it is always assumed that the material cannot be compacted.
The forging process of DEFORM finite element software provided with the properties of porous material to provide the possibility of loose defect.But the material with such attributes is always used for simulating the procedure of powder metallurgy.
Ingot material is 30Cr2Ni4MoV.

Introduction With science and technology development, great concrete structure using in a variety of harsh environments is increasing such as cross-sea Bridge, tunnel, offshore oil platform, toxic and hazardous waste disposal and treatment engineering [1].
Raw materials and test methods Raw materials P·Ⅰ52.5 Cement, Shandong Shanshui card, specific surface area is 370m2/kg, 3d compressive strength is 38.4 MPa, 28d compressive strength is 54.9MPa.I grade fly ash, produced by Shandong Weifang power plant, density is 2.2 g/cm3, fineness is 2.2 g/cm3, water demand ratio is 96%.S95 ground slag, density is 2.8 g/cm3, specific surface area is 368 m2/kg.Medium sand, produced by Jimo, fineness modulus is 2.9, mud content is 10%.Polycarboxylates high-performance water-reducing agent, water reducing rate is 32%.5-10mm gravel, limestone, particle size distribution is good, water absorption is 0.65%,mud content is 0.3%.10-20mm gravel, limestone, particle size distribution is good, crushing value is 11.8%, apparent density is 2700 kg/ m3 , packing density is 1470kg/ m3, water absorption is 0.49%.
Analysis shows that unburned material in carbon go up surface when the concrete workability is poor.
Adopting cementitious system compatibility material and good quality admixture, mixture ratio optimization can achieve good job of high performance concrete.
