Fracture toughness, rather than strength, is often the limiting factor of structural materials.
Developing new base materials with improved fracture toughness often takes more than a …

It is now a well-established fact that even simple topology variations can drastically change
the fracture response of structures. With the objective of gaining quantitative insight into this …

We propose an asymptotic homogenization framework to simulate the fracture of
heterogeneous materials. This framework upscales the phase field model for microscale …

In this work, we explore the possibility of controlling toughening mechanisms in brittle
materials through microstructure design to enhance their resistance to crack growth. First, a …

We investigate the elastic–plastic fracture of architected materials through experiments and
theory, with a focus on understanding the combined effects of material length scale and …

Video motion magnification amplifies invisible small motions to be perceptible, which
provides humans with a spatially dense and holistic understanding of small motions in the …

Brittle solids are often toughened by adding a second-phase material. This practice often
results in composites with material heterogeneities on the meso scale: large compared to …

We use a combined theoretical and experimental approach to investigate the quasi-static
peeling behaviors of heterogeneous films from corrugated substrates. The heterogeneity is …

Soft layered material systems are ubiquitous in nature and engineering–from natural
biological tissues to engineered devices. However, from the mechanics perspective, why …

A rational design for simultaneous toughening and strengthening in composites would be
significant for myriad applications in fracture-related problems. Nacre simultaneously …
