Abstract The aim of this short review is to summarize the developing theory aimed at describing the eﬀect of plastic events in amorphous solids on its emergent mechanics. Experiments and simulations present anomalous mechanical response of amorphous solids where quadrupolar plastic events collectively induce distributed dipoles that are analogous to dislocations in crystalline solids. The novel theory is described, and a number of pertinent examples are provided, including the comparison of theoretical prediction to simulations or experiments.

无定形固体的弹性、塑性和筛分：简评

摘要本短文旨在总结正在发展的理论，这些理论旨在描述非晶态固体中的塑性事件对其出现的力学的影响。实验和模拟显示了非晶体的异常力学响应，其中四极塑性事件共同诱发了分布式偶极子，类似于晶体固体中的位错。报告阐述了这一新颖理论，并提供了大量相关实例，包括理论预测与模拟或实验的比较；

期刊介绍： General physics – physics of elementary particles and fields – nuclear physics – atomic, molecular and optical physics – classical areas of phenomenology – physics of gases, plasmas and electrical discharges – condensed matter – cross-disciplinary physics and related areas of science and technology. Letters submitted to EPL should contain new results, ideas, concepts, experimental methods, theoretical treatments, including those with application potential and be of broad interest and importance to one or several sections of the physics community. The presentation should satisfy the specialist, yet remain understandable to the researchers in other fields through a suitable, clearly written introduction and conclusion (if appropriate). EPL also publishes Comments on Letters previously published in the Journal.
