Tissue engineering has been driving a growing interest in mesoscale tissue mechanics (10^−4^ – 10^−2^ m), requiring tools to compare modulus between irregularly shaped primary tissue explants and synthetic scaffolds. We have designed and built a simple cantilever-based mesoscale indentation device to record…

Tough hydrogels have emerged as a promising class of materials to target load-bearing applications, where the material has to resist multiple cycles of extreme mechanical impact. A variety of chemical interactions and network architectures have been used to enhance the mechanical properties and fracture mechanics of…

'Leonard Azamfirei' 'Hermann Ehrlich' 'Maria Grazia Cascone'] Biomaterials and biomedical devices interact with the human body at different levels. At one end of the spectrum, medical devices in contact with tissue pose risks depending on whether they are deployed on the skin or implanted. On the other hand, food…

The characterization of mechanical properties in soft 3D printed materials at the microscale remains a significant challenge due to the lack of standardized methodologies. To address this issue, a microscale nanoindentation protocol for elastomeric 3D printed microstructures is developed, optimized, and benchmarked.…

Mechanical properties of soft biological tissues play a key role in their normal physiology, contributing to their formation during development, maintenance and repair during adult homeostasis, and driving diseases such as cancer. Mechanics has been proposed to exert its effect by impacting cells fate decisions and…

Mushrooms are increasingly recognized as delicious, nutritious, and sustainable foods, with an intrinsic umami flavor and fibrous microstructure that can approximate meat-like texture. Among them, lion’s mane mushroom has emerged as a promising candidate for whole-cut meat alternatives. Yet, its mechanical…

Les faibles propriétés dans l'épaisseur des stratifiés en termes de rigidité, de résistance à la fatigue et à l'impact, impliquent dans le cadre des pièces épaisses une sensibilité au délaminage. Cette problématique a conduit à l'émergence de préformes tridimensionnelles (3D) disposant de renfort dans l'épaisseur…

The texture of meat is one of the most important features to mimic when developing meat analogs. Both protein source and processing method impact the texture of the final product. We can distinguish three types of mechanical tests to quantify the textural differences between meat and meat analogs: puncture-type…

This study investigates methodological variability across various expert laboratories worldwide, with regards to characterizing the mechanical properties of biological tissues. Two testing rounds were conducted on the specific use case of uniaxial tensile testing of porcine aorta. In the first round, 24 labs were…

We propose Material Fingerprinting, a new method for the rapid discovery of mechanical material models from direct or indirect data that avoids solving potentially non-convex optimization problems. The core assumption of Material Fingerprinting is that each material exhibits a unique response when subjected to a…

Stretchable electronics require sophisticated fabrication strategies to achieve both high electrical performance and mechanical compliance. While various approaches exist, from geometric designs to composite materials, most face challenges in balancing fabrication complexity with device performance. Here, we present a…

Bolt connections are widely used in construction and engineering to securely join structural elements. These connections are essential for distributing loads across components and ensuring that structures can withstand external forces. The planned failure of these bolts is of great importance in steel safety barriers…

Construction materials like steel and concrete have been used for thousands of years; however, their industrial-scale production began relatively recently in the 19th century. These materials are still being improved as the drive to build taller buildings, longer bridges, larger dams, and similar engineering marvels…

Understanding the thermomechanical behavior of heterogeneous polymer systems is crucial for material design. Herein, we introduce a novel technique that couples chemistry-selective infrared (IR) heating with atomic force microscopy (AFM) nanomechanical measurements. We demonstrate that surface temperature of the sample…

models Authors: ['Royal Chibuzor Ihuaenyi' 'Wei Li' 'Martin Z. Bazant' 'Juner Zhu'] Efficient and accurate learning of constitutive laws is crucial for accurately predicting the mechanical behavior of materials under complex loading conditions. Accurate model calibration hinges on a delicate interplay between the…

Understanding sub-cellular mechanics is crucial for a better understanding of a variety of biological functions and dysfunctions. A structure-function analysis of the cytoskeletal protein networks provides not only ways to deduce from its structure insights into its mechanical behaviour but potentially also new…

Nacre-like aluminas are bio-inspired, ceramic-based composites that display high toughness and strength. Their toughness arises from their brick-and-mortar microstructure. We must understand the role of several microstructural features over their mechanical properties. Techniques that allow microstructural imaging…

The lifetime of most metals is limited by cyclic loads, ending in fatigue failure. The progressive growth of cracks ends up in catastrophic failure. An advanced method is presented for the determination of cyclic crack growth on the microscale using a nanoindenter, which allows the characterization of>10,000 loading…
