, 1997 在岩土力学与渗流力学相结合的基础上，建立了油藏渗流与应力耦合作用的数学模型，给出了耦合分析的数值模型和数值求解的思路和步骤。要实现这一耦合分析过程，建立了单元平衡方程，给出了单元等效结点力的计算表达式，对表达式中的自重载荷、孔隙压力载荷、表面力载荷分别进行了分析，并对初应力载荷进行了计算。根据这些计算方法，在建立了单元刚度矩阵、计算了单元等效结点力、形成单元平衡方程之后，将这些方程集合起来，形成总体平衡方程。通过对总体平衡方程求解，即得各结点的位移值及应变、应力场分布。根据有限元的基本理论 ...

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT A thermomechanical strategy based on rolling‐annealing cyclic (RAC) was developed to regulate defect architecture and precipitation behavior in a (FeCoCrNi)94Al3Ti3 high‐entropy alloy. Intermediate annealing during rolling enables progressive grain refinement and introduces a high density of twins, stacking faults, and dislocations, forming a ...

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT The exceptional ductility of face‐centered cubic high/medium‐entropy alloys (H/MEAs) is counterbalanced by intrinsically restrained yield strength, fundamentally compromising their application in structural and functional materials. Here, a novel carbon (C)‐driven precipitation strategy is introduced to promote discontinuous precipitation (DP)
