基于最小耗能原理的混凝土损伤演变方程

Establishing the damage developing equation of concrete through the principle of minimum dissipation of energy

以混凝土的各向同性弹性损伤为例,提出了一种基于最小耗能原理建立损伤演变方程的新思路,并推导得到了混凝土在单向拉伸下的损伤演变方程.

Taking concrete's isotropic elastic damage as example, this article puts forward a new thought of establishing the damage developing equation on the basis of the principle of minimum dissipation of energy, and infers the concrete's damage developing equation under uniaxial extension.
