Influence of crosslinking on the stiffness and degradation of dermis‐derived hydrogels
Journal of Biomedical Materials Research Part A, 2013Natural hydrogels have been investigated for three‐dimensional tissue reconstruction and regeneration given their ability to emulate the structural complexity of multi‐component extracellular matrices (ECM). Hydrogels rich in ECM can be extracted and assembled from soft tissues, retain a composition specific to the tissue source, and stimulate ...

Change in stiffness and effect of orientation in degrading polylactide films
Biomaterials, 1998The degradation pattern of the synthetic absorbable polyester is thought to occur from the center of the material outward, and the bulk degradation is therefore attributed largely to the chemical composition of the material. It was hypothesized that this pattern might be altered by changing the morphology of the material, i.e., by introducing molecular

Stiffness degradation and shear strength of silty sands
Canadian Geotechnical Journal, 2004Soils behave nonlinearly from very early loading stages. When granular soils contain a certain amount of fines, the degree of nonlinearity also changes, as stiffness and strength characteristics vary with fines content. Hyperbolic stressstrain models and variations of these models are often used for description of the nonlinear behavior.

Modeling Stiffness Degradation in Filamentary Composite Materials
Journal of Materials in Civil Engineering, 1992The effect of service‐load‐induced internal damage in advanced filamentary composite materials has for some time been a topic of extensive research. It is well known that the stiffness of the material system is degraded as load is applied and damage accumulates.

Water effects on rock strength and stiffness degradation
Acta Geotechnica, 2015Reduction in strength and stiffness in rocks attributed to an increase in water content has been extensively researched on a large variety of rock types over the past decades. Due to the considerable variations of texture and lithology, the extent of water-weakening effect is highly varied among different rock types, spanning from nearly negligible in ...

Journal of Reinforced Plastics and Composites, 1997
The study on property degradation of damaged composite laminates is extended to anisotropic laminates with matrix cracking. In Part 2 of the paper, a solution for partitioned stiffnesses is given to complete the constitutive relations developed in Part 1.

Strain path dependent stiffness degradation of a loaded sheet
International Journal of Material Forming, 2008Material stiffness is an important material property especially in analyses of springback, due to its influence on a final result. Despite all that, the elastic response of the formed part associated with the forming tools removal is in the most of computational analyses still performed by Hooke’s law and with initial values of elastic constants used ...

Stiff Degradation of Granular Material – A DEM Approach
2019The stiffness degradation of granular materials such as soils due to cyclic loading has been widely explored in the experimental studies, mostly in triaxial or oedometer apparatus. Such behaviour can be observed due to the cyclic loading at very small strains, which is considered as elastic range.

Stiffness Degradation in CFRP Laminates Subjected to Fatigue Loading
Volume 4: Advanced Materials: Design, Processing, Characterization and Applications; Advances in Aerospace Technology, 2023Abstract Reinforced polymer composite materials are widely used in aerospace, marine or other civilian structures, as it offers the advantage of tailor-suiting to the design requirements. During service, they undergo damage due to service loading, environment as well as accidental bird hit (in case of aircraft), and tool drops during ...
