Soil precompression stress assessed from strain‐stress data in linear scale: The need for a physically based approach

Soil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract State‐of‐the‐art models for soil compaction express soil strength by the so‐called precompression stress. The idea is to avoid stresses higher than those previously exposed to the soil. However, the quantification of soil precompression stress generally implies a problematic logarithmic transformation of the applied stress.

How Does Heterogeneity Control Strain Localization Patterns in High‐Porosity Rocks?

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract We aim to explore how heterogeneous porosity and grain size contribute to strain localization patterns in highly porous rocks based on phase‐field simulations. The strain localization patterns, including shear bands, dilatation bands, and compaction bands, are commonly observed in geological field studies and laboratory experiments.

Avaliação da compressibilidade de um Nitossolo Vermelho distroférrico sob sistema plantio direto, preparo convencional e mata nativa Evaluation of compressibility of a dystroferric Red Nitosol under no-tillage and conventional tillage systems and a native forest

Revista Brasileira de Ciência do Solo, 2005
Os efeitos do tráfego de máquinas nos atributos do solo de acordo com o tempo de adoção do sistema plantio direto são ainda pouco pesquisados em ambientes tropicais, e muitas dúvidas ainda persistem sobre a variação dinâmica da estrutura do solo e a sua ...

Consolidômetro: equipamento pneumático-eletrônico para avaliação do estado de consolidação do solo Consolidometer: electronic-pneumatic equipment to evaluate soil consolidation

Revista Brasileira de Ciência do Solo, 2007
A obtenção da pressão de preconsolidação (sigmap) se dá a partir de um método denominado ensaio de consolidação, cuja definição consiste no processo de transferência gradual de uma carga aplicada ao solo até que todos os vazios deste sejam comprimidos. O

Extended Kelvin–Voigt Model for Simulating Thermally Accelerated Creep in Fine‐Grained Soils

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 4, Page 1843-1854, March 2026.
ABSTRACT The subsurface undergoes temperature variations in many situations due to anthropogenic and natural causes, which strongly influence the long‐term behavior of soils. These phenomena can involve temperature anomalies in the ground across distances of a few meters, as in the case of nuclear waste repositories, to distances encompassing entire ...

Soil compaction due to forest harvest operations Compactação do solo em conseqüência das operações de colheita florestal

Pesquisa Agropecuária Brasileira, 2007
The objective of this work was to determine, through the use of the bearing capacity model, the traffic effects of the forest harvest operations on the preconsolidation pressure (sigmap), during one cycle of the eucalyptus plantation.

A pilot study of chemoimmunotherapy in the postconsolidation setting for high‐risk neuroblastoma (ANBL19P1): A report from the Children’s Oncology Group

Cancer, Volume 132, Issue 2, 15 January 2026.
Abstract Background Survival for patients with high‐risk neuroblastoma remains poor despite current‐era multimodality treatment that includes postconsolidation GD2‐directed immunotherapy. Given the promising responses in patients who receive dinutuximab‐based chemoimmunotherapy in the relapsed setting, the Children’s Oncology Group ANBL19P1 study ...
