| Abstract: | We considered the finite timeblow up of solutions to a class of parabolic type Kirchhoff equations with general nonlinearity. By using the first order differential inequality and convexity arguments, we gave some sufficient conditions for the solutions to blow
up in finite time, and obtained the upper bound estimate of the blow up time. |

| Keywords: | Kirchhoff equation general nonlinearity blow up upper bound |
