J. Cent. South Univ. (2012) 19: 1098-1108 DOI: 10.1007/s11771-012-1115-1 A plasticity model for sand-structure interfaces A. Lashkari Department of Civil & Environmental Engineering, Shiraz... role is transferring loads from structures to soil masses. An interface model within the bounding surface plasticity framework and the critical state soil mechanics is presented. To this aim, general......

%TiB2p/6061Al composites are 120 GPa, 472.6 MPa and 9.79%, respectively, which show high strength and plasticity. A lot of dimples and a few cracked particles are observed on the fracture surfaces of the composites, which indicates good plasticity of the composites. The high strength and plasticity of TiB2p/6061Al composites are attributed to good bonding between TiB2 particles and aluminum alloy. Key......
refinement; plasticity formability 1 Introduction Mg-14Li-1Al (LA141) alloy has low density of 1.35 g/cm3, which is much lower than that of general magnesium alloys like AZ31 and ZK60. Meanwhile, this alloy is a single phase alloy and its main phase is β(Li) phase with a BCC crystal structure and good plasticity. Therefore, it has been used in many products for aeronautic and astronautic equipment......
the plasticity increases. When the alloy is solution treated at 900 ℃ and then aged, the main microstructure is Widmanstatten with coarse β grain and the strength can reach 1 400 MPa with water cooling and air cooling methods. When the alloy is solution treated at 820 ℃ and then aged, the microstructure is bi-modal with good plasticity. The alloy has better balance of strength and plasticity under aging......
