The rheological behavior of wood emerges from complex mechanical interactions occurring across multiple length scales. This behavior is characterized by directional dependence, as well as sensitivity to moisture content, loading time, and t...
Simulation of time-fractional oxygen diffusion in cornea coated by contact-lens [0.03%]

Alireza Daneh-Dezfuli et al.
In this paper, the time-fractional oxygen diffusion has been simulated in a one-dimensional (1D) corneal-contact lens (CL) system. Different CLs have been employed as Balafilcon, thin- and thick-Polymacon. It is assumed that homogeneous and...
An anisotropic linear thermo-viscoelastic constitutive law: Elastic relaxation and thermal expansion creep in the time domain [0.03%]
各向异性的线性热粘弹性本构定律：时间域中的弹性松弛和热膨胀蠕变
Heinz E Pettermann,Antonio DeSimone
Heinz E Pettermann
A constitutive material law for linear thermo-viscoelasticity in the time domain is presented. The time-dependent relaxation formulation is given for full anisotropy, i.e., both the elastic and the viscous properties are anisotropic. Thereb...
Effect of fiber-matrix adhesion on the creep behavior of CF/PPS composites: temperature and physical aging characterization [0.03%]
纤维与基体粘结对CF/PPS复合材料蠕变行为的影响：温度和物理老化表征

M H Motta Dias et al.
The influence of fiber-matrix adhesion on the linear viscoelastic creep behavior of 'as received' and 'surface modified' carbon fibers (AR-CF and SM-CF, respectively) reinforced polyphenylene sulfide (PPS) composite materials was investigat...
Limit case analysis of the "stable indenter velocity" method for obtaining creep stress exponents from constant load indentation creep tests [0.03%]
"稳定压头速度"法在恒定载荷蠕变实验中获取蠕变应力指数的极限情况分析
J Campbell,J Dean,T W Clyne
J Campbell
This study concerns a commonly-used procedure for evaluating the steady state creep stress exponent, n , from indentation data. The procedure involves monitoring the indenter displacement history under constant load and making the assumptio...
Time-dependent damage in predictions of fatigue behaviour of normal and healing ligaments [0.03%]
时间依赖性损伤在正常和修复期韧带疲劳行为预测中的作用
Gail M Thornton,Soraya J Bailey,Timothy D Schwab
Gail M Thornton
Ligaments are dense fibrous tissues that connect bones across a joint and are exposed daily to creep and fatigue loading. Ligaments are tensile load-bearing tissues; therefore, fatigue loading will have a component of time-dependent damage ...
A computational study of crimping and expansion of bioresorbable polymeric stents [0.03%]
可降解聚合物支架的压花和扩张的计算研究
T Y Qiu,M Song,L G Zhao
T Y Qiu
This paper studied the mechanical performance of four bioresorbable PLLA stents, i.e., Absorb, Elixir, Igaki-Tamai and RevaMedical, during crimping and expansion using the finite element method. Abaqus CAE was used to create the geometrical...
