Abstract: We considered the finite time blow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.

Key words: Kirchhoff equation, general nonlinearity, blowup, upper bound
