ABSTRACT=<p>We study the local load sharing fiber bundle model and its energy burst statistics. While it is known that the avalanche size distribution of the model is exponential, we numerically show here that the avalanche size (<italic>s</italic>) and the corresponding average energy burst (〈<italic>E</italic>〉) in this version of the model have a non-linear relation (〈<italic>E</italic>〉 ~ <italic>s</italic><sup><italic>γ</italic></sup>). Numerical results indicate that <italic>γ</italic> ≈ 2.5 universally for different failure threshold distributions. With this numerical observation, it is then possible to show that the energy burst distribution is a power law, with a universal exponent value of −(<italic>γ</italic> + 1).</p>
