Elastomeric networks that have imbedded particles are considerably more difficult to model than unfilled networks because the imbedded particles deform the trajectory of the chains. Any treatment must incorporate this dual nature of the network. Our work will address this important issue with particular reference to two important materials - liquid crystalline elastomers and bread dough. We aim to produce an accurate mathematical description of filled soft viscoelastic solids, which include compressibility and yielding - two important new features.

具有嵌入颗粒的弹性体网络比未填充的网络更难以建模，因为嵌入颗粒使链的轨迹变形。任何治疗都必须考虑到网络的这种双重性质。我们的工作将解决这个重要的问题，特别是两个重要的材料-液晶弹性体和面包面团。我们的目标是产生一个准确的数学描述填充软粘弹性固体，其中包括压缩性和屈服-两个重要的新功能。
