In this work, we present a novel approach of utilizing the snap-through instability of soft ME materials to enhance their electric responses in low-frequency magnetic environments. This snapping soft ME material, also called the snapping ME electret (SMEE), is designed as an elastomeric arch with tunable residual magnetic flux density and embedded net charges. The high performance of SMEEs stems from fact that, when staying at a critical instability state, any small magnetic perturbation would induce the snap-through behavior of it and generate high-frequency electrical pulses. Here, a theoretical model based on the instability mechanics of SMEEs is presented and used to predict the strong ME coupling effect near its critical state. Experiments are also conducted to confirm the enhanced ME coupling of SMEEs across a broad range at extremely low frequencies. The SMEE proposed here demonstrates an interesting and effective mechanical pathway to amplify and tune the coupling between magnetic and electric fields.</div></div>","PeriodicalId":17331,"journal":{"name":"Journal of The Mechanics and Physics of Solids","volume":"196 ","pages":"Article 106043"},"PeriodicalIF":5.0,"publicationDate":"2025-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143031433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The latter is exemplary chosen as a combination of the Hosford–Coulomb and Cockcroft–Latham–Oh failure criteria for the high and low stress triaxiality range, respectively, to cover the wide stress range encountered in forming. Damage is coupled to elasto-plasticity to capture the damage-induced degradation of the stiffness and flow stress.

Consequently, especially for highly ductile materials, where substantial necking and localisation precede material fracture, the failure prediction is enhanced. The resulting stress softening is regularised by gradient-enhancement to obtain mesh-objective results. The analysis of a modified punch test experiment emphasises how the damage-induced softening effect can strongly alter the actual stress state towards failure.

We validated the proposed model with examples of concrete fracture, fire-induced damage and fire-induced mechanical property degradation.

Simulation results indicate that fire-induced damage originates in the interfacial transition zone and propagates radially, ultimately resulting in a failure pattern of mesh cracks and local spalling. The corrosion-induced damage extent influences the fire-induced damage evolution process, spalling location and fire-induced damage extent, while the aggregate volume fraction primarily affects damage extent.
