致力于高分子及其复合材料领域的基础性和应用基础性研究工作。在纤维增强树脂基复合材料的设计-制备-结构-缺陷-性能-破坏的集成研究、聚合物物理凝胶化机理与过程调控、高分子材料反应加工过程数值模拟与优化设计、橡胶硫化过程集成研究等方面取得了多项创新性研究成果：
（1）采用断裂影响叠加技术、有限元方法和Monte
Carlo方法相集成的研究方案，数值分析了基体缺陷含量及其分布、纤维缺陷含量及其分布、界面粘结强度及其分布等因素对复合材料力学性能的影响，以及拉伸速率、纤维体积含量与分布状态等因素对复合材料破坏模式的影响，获得了复合材料结构-缺陷-性能之间的定量关系，有助于航空航天、交通等领域的复合材料结构设计。代表性研究成果是期刊论文：Mat. Sci. Eng. A, 2006, 425：178-184；J. Appl. Polym. Sci., 2007, 103： 64-71；Macromol. Mater. Eng., 2006, 291：510-516；Polymer, 2006,47：6218-6225；Polym. Compos., 2008, 29: 649-654；Polym. Compos., 2008, 29: 964-971; Macromol. Mater. Eng., 2008, 293: 194-205。该方面工作的学术创新性被Leon Mishnaevsky Jr. 和Povl Brondsted在论文Micromechanical modeling of damage and fracture of unidirectional fiber reinforced composites: A review, Computational Materials Science, 2009, 44: 1351-1359里详细评论如下：“The BIS (break influence superposition) technique has been combined with FEM (finite element method) by Jia et al. Jia and colleagues modeled the stress transfer from broken to unbroken fibers in fiber reinforced polymer matrix composites. The damage evolution in composites, including the fiber fracture, damage cracking and interface debonding, was simulated using FEM combined with the Monte-Carlo technique. The authors observed in the numerical experiments, that while both low and high interface sliding strengths lead to the decrease of the composite strength (due to the large scale debonding and matrix cracking), the moderate interface sliding strength weakens the negative effect of the fiber fracture on the composite strength.”直译为:“贾玉玺与其合作者把断裂影响叠加技术与有限元方法结合起来。他们模拟了在纤维增强聚合物基复合材料中从已断纤维到未断纤维的应力传递现象。他们采用有限元方法与Monte-Carlo方法相结合的研究方案，模拟了在复合材料里的损伤演变过程，包括纤维断裂、损伤裂纹扩展和界面脱粘。这些作者们在数值实验里观察到：过低的和过高的界面滑移强度都将导致复合材料强度的降低（由于大幅度的界面脱粘和基体开裂），然而适中的界面滑移强度能弱化纤维断裂对复合材料强度的负面影响.”
（2）根据树脂传递模塑工艺的树脂浸润纤维织物的多层次特点，在细观层次上建立了树脂在纤维束内与束间耦合流动的数学模型，分析了充填速度、流体黏度、纤维束尺寸、束内渗透率等参数对流体压力和前沿的影响规律。在宏观层次上建立了树脂在纤维预制体与模腔边缘区域耦合流动的数学模型，研究了边缘通道宽度、树脂黏度、化学反应速率与程度等参数对流动前沿、树脂压力和充填时间的影响，有助于纤维复合材料制备工艺的优化设计，从而推动纤维复合材料在航空航天、交通等领域中的大规模应用。代表性研究成果是期刊论文：Mat. Sci. Eng. A, 2006, 435-436: 515-520；Mat. Sci. Eng. A, 2008, 478:384-389；J. Appl. Polym. Sci., 2009, 113: 3815-3822。该方面工作的学术创新性被 Golestanian Hossein和Poursina Mehrdad在期刊论文Neural network analysis application to permeability determination of fiberglass and carbon preforms, Chinese Journal of Polymer Science, 2009, 27: 221-229里详细评述如下：Jia et al. performed resin flow analysis in rectangular molds. They considered two types of resin flow in the preform, namely the inter-tow and intra-tow. These investigators studied the effects of filling velocity, resin viscosity and intra-tow permeability on resin flow behavior. Their results show that the flow front difference between the inter-tow and intra-tow becomes larger as the intra-tow permeability decreases. Increase of filling velocity and inter-tow dimensions also resulted in an increase in the difference between two flow fronts. 直译为：“贾玉玺和其合作者对矩形模腔中的树脂流动进行了分析。他们考虑了在纤维预制件中树脂流动的两种类型，分别命名为束间流动和束内流动，研究了充模速度、树脂粘度和束内渗透率对树脂流动行为的影响。他们的研究结果显示：随着束内渗透率的降低，束间和束内树脂流动前沿的差别增大；充模速度和束间尺寸的增大也会导致这两种流动前沿的差别增大”。
（3）实现了在聚合、接枝、交联等多种类型的化学反应过程中高分子材料的宏观物理力学性能-微观化学结构-反应加工技术的集成研究，定量揭示了在橡胶硫化、塑料反应挤出、树脂固化等加工过程中材料微观结构、宏观性能的演变规律，数值分析了在复杂外场条件下高分子材料的化学流变行为以及化学热效应、凝胶效应等复杂现象。进而以橡胶硫化过程的有限元模拟方法作为目标函数求解方法，以遗传算法作为材料组分和反应加工条件的搜索寻优方法，建立了橡胶硫化过程的优化设计系统。代表性研究成果是期刊论文：Acta Mater., 2004, 52: 4153-4159; Polym.-Plast. Techn. Eng., 2003, 42: 883-898; Eur. Polym. J., 2009, 45: 1759-1764; Macromol. Theory Simul., 2009, 18: 268-276; Polymer, 2003, 44: 319-326；Polymer, 2002, 43: 7515-7520；Polym. Int., 2004, 53: 41-47；Macromol. React. Eng., 2007, 1: 321-330；J. Mater. Process. Technol., 2008, 199: 56-63；Macromol. Theory Simul., 2007, 16: 785-796；J. Appl. Polym. Sci., 2007, 103: 2331-2336；Mat. Sci. Eng. A, 2007, 454-455: 221-226；Polym. Eng. Sci., 2007,47: 667-674；Polym. Int., 2007, 56: 1553-1557；Polym.-Plast. Techn. Eng., 2005, 44: 447-462; Polymer, 2009, 50: 2181-2189. 该方面工作的学术创新性被K. Mitra在论文Genetic algorithms in polymeric material production, design, processing and other applications: a review, International Materials Reviews, 2008, 53: 275-297里详细评论如下:“Jia et al. solved a weight based multiobjective optimisation problem for producing silicone rubber based on given requirements. They derived the explicit expressions between composition and mechanical properties of silicone rubber from the physics of polymer elasticity and deduced the implicit expressions among material composition, reaction conditions and reaction efficiency from chemical thermodynamics and kinetics. The multi-objective problem was to find out optimal values for material composition and reaction conditions (average number of structure units in an initial molecule, an average number of cross-linkable structure units in an initial molecule, reaction medium temperature) by achieving simultaneous minimisation of the difference between the model predicted shear modulus and reaction time and their corresponding desired values.” 直译为:“贾玉玺与其合作者以硅橡胶制品的反应加工制备为例，按照给定的要求，求解了基于权重的多目标优化问题。他们根据聚合物弹性的物理学原理，获得了材料体系组分和力学性质之间的显式函数关系式；而且，他们还根据化学热力学和动力学理论，建立了材料体系组分、反应加工条件和反应效率之间的隐式表达式。他们求解的多目标优化问题是要同时得到材料体系组分和反应加工条件的最优解（在初始分子里结构单元的平均数量、在初始分子里可交联的结构单元的平均数量、反应加工介质温度）。他们采用了基于优化模型而预测的剪切模量、反应加工时间与相应的期望值之间差异的同时最小化方法，得到了上述多决策变量的最优解。”
