Projectile size effect is of great importance since the scaling researches are extensively applied to concrete penetration investigations. This paper numerically deals with the projectile size effect on penetration resistance via the recently developed Lattice Discrete Particles Model(LDPM) which is featured with mesoscale constitutive laws governing the interaction between adjacent particles to account for cohesive fracture, strain hardening in compression and compaction due to pore collapse. Simulations of two different penetration tests are carried to shed some light on the size effect issue. The penetration numerical model is validated by matching the projectile deceleration curve of and predicting the depth of penetration(DOP). By constant velocity penetration simulations, the target resistance is found to be dependent on the projectile size. By best fitting numerical results of constant velocity penetration, a size effect law for target resistance is proposed and validated against literature data. Moreover, the size effect is numerically obtained in the projectile with longer extended nose part meanwhile the shorter extended nose is found to improve the DOP since the projectile nose is sharpened.

Journal of Rare Earths 2018年第7期36卷 772-780页

作者： Xirong bao jun'an Wang Xiaodong Wang feng Guo Yongzhen Liu Institute of Materials School of Materials Science and EngineeringShanghai University School of Material and Metallurgy Inner Mongolia University of Science and Technology School of Materials Science and Engineering Inner Mongolia University of Technology School of Mining and Coal Inner Mongolia University of Science and Technology

Effects of lanthanum（La） as micro-alloying element on the hot deformation behaviour of the high strength Mn-Cr-Mo bainitic rail steel were investigated under a range of deformation conditions. The results indicate that La increases the flow stress by 10-30 MPa through strengthening nanoscale strain induced precipitation（SIP） θ-（Fe,La）3 C during hot deformation. The hot deformation activation energy increases by 10-40 kJ/mol due to the ＂Zener effect＂ of SIP and the dynamic recrystallization（DRX） is retarded due to the competitive behaviour between SIP and DRX. Bainite plates in the DRX domain can be refined by adding La, resulting in the improvement of hot workability. The DRX domain with peak power dissipation efficiency of 52% is determined to be the optimal processing region for Mn-Cr-Mo-La bainitic rail steel.
