基本力学性能是影响材料承载能力和结构性能的重要因素。 承载能力是指材料

Basic mechanical properties are important factors that affect the load-bearing capacity and structural performance of materials. Load-bearing capacity means that the material has sufficiently high strength, modulus and ductility values ​​under application-related loading conditions. A particularly common loading condition for composite panels or boards is bending (bending). For example, when the wing of an airplane is hit by a bird during flight, it will bend, when the ground of the airplane is hit by a heavy object (such as a hammer), and when the car is driving on a bridge (the bending of the deck) ), Bending also occurs. During the bending process, one surface is in a stretched state, while the other surface is in a compressed state, as shown in Figure 3.1. For concrete columns, the important loading conditions are compressive, and stress occurs along the axis of the column, although bending loading can also occur, just like when a car hits the column. When describing mechanical properties, the tensile conditions are not specified, they usually refer to the tensile conditions, except for brittle materials (such as cement-based composite materials), because the compressive strength is much higher than the tensile strength of brittle materials, the amount of compression accounts for leading position.

Basic mechanical properties are important factors that affect material carrying capacity and structural properties. Carrying capacity refers to the material having sufficiently high strength, modulus and ductility values under the loading conditions related to the application. A particularly common composite plate or plate load condition is bent (bending). For example, when an aircraft's wing is hit by a bird during flight, it bends, when the plane's ground is hit by heavy objects such as a hammer, and when the car is traveling on a bridge (the bridge is bent). During bending, one surface is stretched and the other is compressed, as shown in Figure 3.1. For concrete columns, the important loading conditions are compressed and stress occurs along the axis of the column, although bending loads can also occur, as is the case with a car hitting a column. When describing mechanical properties, the stretch conditions are not specified, which usually refers to stretching conditions, except for brittle materials (e.g. cement-based composites), where compression dominates because the tensile strength of the compression strength is much higher than that of brittle materials.

The basic mechanical properties are the important factors that affect the bearing capacity of materials and structural properties. Bearing capacity means that the material has enough high strength, modulus and ductility under the application related loading conditions. A particularly common loading condition for composite plates or plates is bending (bending). For example, when the wing of an aircraft is hit by a bird in flight, when the ground of the aircraft is hit by a heavy object (such as a hammer), and when the car is driving on a bridge (the bending of the bridge deck), it will also bend. During bending, one surface is in tension while the other is in compression, as shown in Figure 3.1. For concrete columns, the important loading condition is compression, and the stress occurs along the axis of the column, although the bending load will also occur, just like the case of a car hitting the column. When describing the mechanical properties, the tensile conditions are not specified. They usually refer to the tensile conditions, except for brittle materials (such as cement-based composite materials). Because the compressive strength is much higher than the tensile strength of brittle materials, the compression is dominant.
