隨時間變化的材料力學促進了不同學科之間知識的轉移，這些學科處理隨時間變化的固體材料的特性，但從不同的角度進行研究。這些學科包括：機械工程、航空航天工程、化學工程、流變學、材料科學、高分子物理、設計等。該雜志涉及固體聚合物、金屬、陶瓷、混凝土、木材或其復合材料的隨時間變化的力學性能。人們認識到，某些材料可以作為溫度和/或壓力的函數處于熔融狀態。貢獻涉及與加工和熔化到固體轉變行為以及與時間相關的失效和斷裂現象有關的基本問題。

Mechanics of Time-Dependent Materials promotes the transfer of knowledge between various disciplines that deal with the properties of time-dependent solid materials but approach these from different angles. Among these disciplines are: Mechanical Engineering, Aerospace Engineering, Chemical Engineering, Rheology, Materials Science, Polymer Physics, Design, and others.The journal deals with the time-dependent mechanical properties of solid polymers, metals, ceramics, concrete, wood, or their composites. It is recognized that certain materials can be in the melt state as function of temperature and/or pressure. Contributions address fundamental issues relating to processing and melt-to-solid transition behavior as well as time-dependent failure and fracture phenomena.
