塑印油墨用聚酰胺树脂的研制

随着塑料薄膜包装的兴起,对印刷油墨的需求很为迫切,聚乙烯等薄膜的凹版印刷油墨多采用聚酰胺树脂(PA)作粘结料,而我国如今所用的PA仍多依赖进口,估计每年数百吨。一些制墨厂认为,国产PA现仍存在树脂颜色过深、有臭味。

书画塑印与紫砂壶设计——作品“无相相壶”的创作感悟

紫砂壶的造型离不开中国传统美术,无论是紫砂壶的造型还是装饰,中国传统美术都发挥了十分深刻的影响。在中国传统美术中,以书画艺术作为核心,其中包含的书法、绘画、印签等元素都有着独特的美术价值。除此之外,雕塑艺术在紫砂壶造型及装饰中同样十分重要。笔者通过对作品“无相相壶”的制作,浅谈中国传统书画塑印在紫砂壶设计中发挥的作用。

论“中国陶瓷塑印”的创作和意义

陶瓷的发明创造不但是人类发展进程的标志,更是中华民族文化艺术发展史的完整再现。在陶瓷近万年的发展的历史长河中,点缀着无数颗发明创造的璀璨的新星,使得我们的艺术星空更加绚丽多彩。

Influence of Residual Stress on the Elastic-plastic Response to Indentation

The indentation method is useful in determining the residual stress according to the elastic-plastic properties of materials.So the effect of the residual stress on the elastic-plastic indentation properties of materials was studied by using the finite element method to find better indentation parameters which are strongly induced by the residual stress.The results show that load-depth curve,plastic pile-up,indentation shape,indentation contact stress and indentation residual stress are affected by different residual stress,and these parameters can be used to deduce the residual stress.Also,a special indentation equipment was developed to analyze the elastic-plastic properties of materials with different residual stress,and the experimental results show a good agreement with the FEM results.For practical application,the elastic-plastic indentation properties of materials with unknown residual stress could be obtained by the developed equipment to deduce the residual stress comprehensively.
