Determination of Constitutive Parameters of Crystalline Limestone Based on Improved RHT Model by Hao-Fan Tian, Tai Bao, Zhuo Li, Hao Peng, Shuai You, Shi-li Xiao

“…This study improves the RHT constitutive model based on some shortcomings, and the main improvements work are as follows: (1) hyperbolic function is used to make up for the deficiency of tensile strain rate enhancement factor of RHT constitutive model at high strain rate; (2) considering the constant change of hydrostatic pressure, the initial damage value of rock is introduced into the constitutive model, and the improved damage accumulation expression is derived based on this value. (3) In the equation of residual failure surface, the influence of the Lode angle factor is considered, the RHT constitutive parameters of crystalline limestone are determined by the SHPB experiment, and the difference in rock failure forms before and after the correction of constitutive parameters is simulated by ANSYS/LS-DYNA software. …”

A Software Decoding Error Compensation Method for Resolvers in Automotive Electric Drive Systems by GUO Zhida, CHEN Zhichu, TANG Xionghui, LIU Wang, LI Jing, CHEN Zuoling

“…To address this challenge, this paper analyzes the influence of different integration starting times on the angle output from decoding. Based on a mathematical model established to correlate integration starting times with angular errors in the decoding outputs, an analytical expression is derived for angular errors as a function of integration starting time, which establishes a direct proportional relationship between the two. …”

Study of Post-Peak Strain Softening Mechanical Behaviour of Rock Material Based on Hoek–Brown Criterion by Qibin Lin, Ping Cao, Peixin Wang

“…In order to build the post-peak strain softening model of rock, the evolution laws of rock parameters m,s were obtained by using the evolutionary mode of piecewise linear function regarding the maximum principle stress. Based on the nonlinear Hoek–Brown criterion, the analytical relationship of the rock strength parameters m,s, cohesion c, and friction angle φ has been developed by theoretical derivation. …”
