Secondly, based on the theory of stability, the author proposes a new concept concerning the failure criteria as a solution to eliminate these inconveniences whereby the definitions of failure criteria of the infinitesimal volume element of material, the cross section of member, the single member and the aggregate of members are given. Finally, the parameters to represent the degree of failure of the objects and the subspace generated by the failure modes are discussed.

It is common that reinforced concrete bridges are damaged with steel corrosion which not only reduces the strength of structures but also changes their failure mode if there exists nonsymmetry corrosion developed to some extent. Nonsymmetry corrosion can translate ductile fracture into brittle failure and translate flexural failure into torque failure, etc.

Refers to the independence of failure to complete a single chip damage; the relevance of failure means a failure associated with some other fault, the fault is not normal for many functions, and its failure to control the various functions of the substance of the common part of malfunction caused by (for example, soft, hard disk subsystem is not working properly, and the soft, hard disk controller to control the functions of the more isolated, fault is often on the motherboard that control peripheral DMA data transfer control circuit).

Based on some principal rules of brittle rocks polyaxial tests and previous researches, three controlling failure types for brittle rock are obtained. The first type represents the brittle failure controlled by extension microcrack under the condition of lower hydrostatic pressure; the second represents the ductile failure controlled by friction sliding action under the condition of higher hydrostatic pressure when microcrack is close; and the third represents brittle-ductile failure type controlled by multiple factors mentioned above under the condition of high hydrostatic pressure when some microcracks are open and others are close.

The experimental results show that: the failure mode of strengthened beam at elevated temperature can be classified as flexure failure mode or flexure-shear failure mode, and the failure mode of strengthened beam at high temperature may be different from that at room temperature; and although the load supported by the strengthened specimen is larger than that supported by the unstrengthened specimen, the fire resistance of the strengthened specimen is still larger than that of the unstrengthened specimen, due to the influence of fire insulation.
