Soft amorphous materials are viscoelastic solids ubiquitously found around us, from clays and cementitious pastes to emulsions and physical gels encountered in food or biomedical engineering. Under an external deformation, these materials undergo a noteworthy transition from a solid to a liquid state that reshapes the material microstructure. This yielding transition was the main theme of a workshop held from January 9 to 13, 2023 at the Lorentz Center in Leiden. The manuscript presented here offers a critical perspective on the subject, synthesizing insights from the various brainstorming sessions and informal discussions that unfolded during this week of vibrant exchange of ideas. The result of these exchanges takes the form of a series of open questions that represent outstanding experimental, numerical, and theoretical challenges to be tackled in the near future.
软无定形材料是我们周围普遍存在的粘弹性固体，从粘土和水泥浆到食品或生物医学工程中遇到的乳液和物理凝胶。在外部变形下，这些材料会经历从固态到液态的显著转变，从而重塑材料的微观结构。这种屈服转变是2023年1月9日至13日在莱顿洛伦兹中心举办的一次研讨会的主题。本文献从批判性的角度探讨了该主题，综合了在这一周充满活力的思想交流中展开的各种头脑风暴会议和非正式讨论中的见解。这些交流的结果呈现为一系列开放性问题，代表了在不久的将来需要应对的突出实验、数值和理论挑战。
