A peculiar phenomenon of periodic abrasion is often seen on the circumference of rotating viscoelastic disk under contact load. Many factors such as viscoelastic response of the material, wearing resistance, vibration of the whole system, heat generation due to viscoelastic dissipative energy and unsteady heat conduction are all considered to be responsible on this phenomenon. The author discusses on the first step approach to an extremely complicated type of viscoelastic mixed boundary value problem under non-isothemal condition, developing a new hybrid method for simulation.In 1994, fundamental factors and mechanisms of the complicated phenomenon are made clear adopting an experimental/theoretical hybrid simulation on a model of rotating viscoelastic disk under a contact load. It would be, as the results, pointed out that viscoelastic responses of the material play an important role on the formation both of periodic stress and temperature distribution. Moreover, a type of peculiar vi … More bration is accompanied by the periodic temperature distributions, which could develop easily a type of periodic abrasion on the circumference of the disk.In the second year, the quantitative evaluation not only of time dependent stress/strain but loss energy under traveling load was studied after developing a new experimental/theoretical hybrid method for simulation. Temperature distribution due to heat generation by dissipative energy produced by viscoelastic response of the material is investigated extensively. A computer aided photoviscoelastic method for stress/strain analysis under non-proportional loading condition is also developed on the basis of the well known Diagonal Summation Theorem. Time dependent stress/strain are successfully evaluated near the contact region in a viscoelastic epoxy strip under a traveling load along its straight edge.Several elemental problems involved in the complicated combined phenomena, such as peculiar vibration and periodic distribution of time dependent stress/strain are successfully analyzed, evaluating dissipative energy in a semi-infinite viscoelastic plate under traveling load.

在接触载荷作用下，旋转粘弹性圆盘的周长经常出现周期性磨损的奇特现象。材料的粘弹性响应、耐磨性、整个系统的振动、粘弹性耗散能产生的热量和不稳定的热传导等因素都被认为是造成这种现象的原因。讨论了非等温条件下一类极复杂粘弹性混合边值问题的第一步求解方法，提出了一种新的混合模拟方法。1994年，对接触载荷作用下的旋转粘弹性盘模型进行了实验/理论混合模拟，明确了这一复杂现象的基本因素和机理。结果表明，材料的粘弹性响应对周期性应力和温度分布的形成起着重要作用。此外，一种特殊的振动伴随着周期性的温度分布，这很容易在圆盘的周长上形成一种周期性的磨损。第二年，开发了一种新的实验/理论混合模拟方法，研究了行载作用下应力/应变随时间变化和损失能的定量评价。广泛地研究了材料粘弹性反应产生的耗散能产生热量所引起的温度分布。在对角求和定理的基础上，提出了非比例加载条件下应力应变分析的计算机辅助光粘弹性方法。时间依赖的应力/应变成功地评估了粘弹性环氧树脂条在沿其直线边缘的移动载荷下的接触区域附近。本文成功地分析了半无限粘弹性板在行载作用下的耗散能，并对其特殊振动和时变应力/应变周期分布等复杂组合现象所涉及的几个基本问题进行了求解。少
