本人在學(xué)習(xí)pinho的兩篇文獻(xiàn)《Physically-based failure models and criteria for laminated fibre-reinforced composites with emphasis on fibre kinking: Part I: Development》(簡稱Part I)和《Physically-based failure models and criteria for laminated fibre-reinforced composites with emphasis on fibre kinking: Part II: Implement》(簡稱Part II)的時(shí)候,對文中的3D kinking Model存在以下的疑問:
在Part I中的表達(dá)為:

而在Part II中則是

以上畫圈的地方就是兩篇文章的不同之處,也是本人疑惑的地方,到底是應(yīng)該用哪種形式進(jìn)行纖維扭結(jié)的判斷?
