Most theoretical kinetic approaches proposed so far to describe fragmentation processes rely on the assumption that the fragments can be characterized by a unique relevant variable, for example their size or mass $h$. We investigate the consequences of introducing additional variables by considering a fragmentation model in which the fragments are described by two internal variables, $h,\,w$, and a breakup rate proportional to $h^\alpha w^\beta$. The exact solution, already partly presented in reference [1], is derived and discussed in details with an emphasis on the fragment distribution function. It is shown that, because of the random multiplicative nature of the process, non reduction to an effective one-variable problem is usually poss...
