【摘要】:復(fù)合材料層合板殼是由多種組分材料組合而成.與單一材料的板殼結(jié)構(gòu)相比,它無明確的材料主方向,各層間材料間斷和不連續(xù),具有明顯的幾何非線性和材料非線性等新的特點(diǎn).其失效模式也遠(yuǎn)比單一材料的情況復(fù)雜,具有如基體開裂、脫膠、分層、分層裂紋偏轉(zhuǎn)、多分層以及分層傳播等多種模式.各國學(xué)者基于不同的考慮,提出了多種方法研究復(fù)合材料層合板殼的失效.首先,在簡要介紹了層合板殼線性力學(xué)基本理論的基礎(chǔ)上,重點(diǎn)回顧了層合板殼結(jié)構(gòu)非線性力學(xué)幾種基本理論發(fā)展的過程,主要闡述了經(jīng)典大撓度非線性理論、一階剪切變形理論、高階剪切變形理論、鋸齒理論、廣義分層理論的理論體系及基本公式,并對幾種理論之間的聯(lián)系和差異進(jìn)行了總結(jié);其次,介紹了當(dāng)前層合結(jié)構(gòu)非線性領(lǐng)域的研究進(jìn)展,綜述了典型復(fù)合材料板殼結(jié)構(gòu)的失效機(jī)理及優(yōu)化設(shè)計、復(fù)合材料板殼結(jié)構(gòu)在復(fù)雜環(huán)境下的破壞機(jī)理、復(fù)合材料板殼結(jié)構(gòu)的物理非線性、含脫層纖維增強(qiáng)復(fù)合材料板殼結(jié)構(gòu)的破壞機(jī)理等各研究熱點(diǎn)的最新研究成果;最后,對該領(lǐng)域未來的研究方向進(jìn)行了展望.
[Abstract]:Composite laminated plates and shells are composed of a variety of component materials. Compared with the plate and shell structure of a single material, it has no definite main direction of material, discontinuity and discontinuity of materials between layers, and has new characteristics such as obvious geometric nonlinearity and material nonlinearity. The failure mode is also more complex than that of single material. It has many modes such as matrix cracking, degumming, delamination crack deflection, multi-delamination and delamination propagation. Based on different considerations, many methods have been proposed to study the failure of composite laminated plates and shells. Firstly, based on a brief introduction of the basic theory of linear mechanics of laminated plates and shells, the development process of several basic theories of nonlinear mechanics of laminated plates and shells is reviewed, and the classical nonlinear theory of large deflection is expounded. First order shear deformation theory, high order shear deformation theory, sawtooth theory, generalized stratification theory theoretical system and basic formulas, and the relationship and differences between the several theories are summarized. This paper introduces the research progress in nonlinear field of laminated structures, summarizes the failure mechanism and optimal design of typical composite plate and shell structures, and the failure mechanism of composite plate and shell structures in complex environments. The latest research results on the physical nonlinearity of composite plate and shell structure and the failure mechanism of composite plate and shell structure with delamination fiber are discussed. Finally, the future research direction in this field is prospected.
